1848: And that is about it from me for today. You can keep up with the scores from Roddick-Monfils (currently 1-0 with serve in the first set) and Razzano- Stosur (Stosur won the first set 6-1) on the website. Many thanks for your input, especially the Juan Martin del Potro v Polar Bear chat. Adieu.
1843: Just time to tell you about tomorrow's coverage before we wrap up. Dinara Safina v Victoria Azarenka will be the first match on the Red Button, with Andy Murray v Fernando Gonzalez expected to start on BBC 2 at approximately 1415 BST. There will be commentary on 5 Live Sports Extra, live streaming on the BBC website and of course you can follow it here too. with myself and Piers.
1839:Andy Roddick and Gael Monfils are out on court and knocking up but I'm afraid our live stream on the website and Red Button coverage is finishing. They are unlikely to have time to get that one done and dusted tonight anyway.
1837: "Great win from Cirstea! That had to be one of the longest games in the history of women's tennis! Now bring on Gael 'the coolest name in tennis' Monfils & Andy Roddick!" From Daniel, in Bermondsey, via text on 81111
1832: So Andy Roddick and Gael Monfils will be coming on to Court Suzanne Lenglen next, at 7.30pm Paris time, after waiting around all day. I bet they are thrilled.
1830: Blimey. Jelena Jankovic will have to wait a while longer to end her wait for a Grand Slam. Sorana Cirstea, the 19-year-old world number 41 is into the quarter-finals after finishing off an epic match with a blistering backhand winner. The fifth seed saved two match points, the second with an incredible drive volley, but Cirstea is through, winning 3-6 6-0 9-7.
1822: Just a reminder, Andy Murray's quarter-final against Gonzo is second on Court Philippe Chatrier tomorrow. Play starts at 1300 BST with Dinara Safina's match, so Andy will probably be on at about 1315...only kidding, I'd estimate the British number one will be on around 1500. Full coverage details to follow.
1820: Virginia Razzano of France has just started her fourth-round match with Sam Stosur over on Court Philippe Chatrier. It's 1-1, with serve. Stosur, you might remember, knocked out Elena Dementieva in round three.
1818: "Re 1731- All I can tell you about Cirstea is that she is good friends with Caroline Wozniacki who she knocked out in round three and who is her doubles partner. She seems to be the first of a long line of young Romanian players though." From anon, via text on 81111
1813: What's this? - a looping Cirstea forehand lands in the corner with Jankovic nowhere and the Romanian is suddenly two points away from the last eight at 0-30 up. Janko hauls herself back to 30-all and then we are treated to a 26-shot rally that ends in disaster for Cirstea when she flops a smash into the net. Both players try a bit of moon-ball on the next point, which ends when a Cirstea forehand lands in the net. 7-7. Don't go anywhere folks...
1807: Jankovic holds to take it to 6-6 in decider - the crowd are with the Romanian teenager by the sounds of things, and when Cirstea holds to love in the next game, she is greeted with loud cheers. Jankovic serving again, at 6-7 and this third set has lasted 66 minutes already.
1805: "Useless fact of the day: No matter what happens in the Monfils-Roddick match, this will be the first time since 1986 that eight different countries are represented in the French Open men's quarter finals." From kirkthemag on 606
1803: "Re 1745, I don't think Laura had to take her GCSEs to qualify for the tournament." From Lewis, revising for his A-level in Wimbledon wildcards, via text on 81111
1759: I'm just getting my first look at Cirstea now and I can reveal she has a flair for drop shots but is quite happy slugging it out from the back of the court too. Jankovic to serve at 5-6 in the decider.
1756: Sadly, that wasn't quite the titanic clash I'd hoped for to be honest - Tsonga never really got into his stride, which is a shame. Still, Del Potro does look very good indeed. As for Jankovic, well she imploded in that game I'm afraid...Cirstea won the next four points and we are at 5-5. The teenage Romanian has just saved a break point of her own too.
1752: Another big Juan Martin del Potro forehand is too hot for Tsonga to handle and this one is all over. The Argentine fifth seed is through 6-1 6-7 6-1 6-4 and plays Tommy Robredo in the last eight. Jo-Wilfried Tsonga still gets a big send off from his home crowd. "He'll be back," says Sam Smith on the Red Button.
1750: "Re 1736, well, Del Potro is taller that a mountain that's 6'5" tall. As for the polar bear claim, an arm wrestle is the only way to confirm this." From anon, via text on 81111
1748: Ah, that could be the end for Tsonga, who is broken after putting a drop shot attempt in the net and now trails 5-4 - Del Potro will serve for the match next. Over on Suzanne Lenglen, Jankovic is even closer to victory, serving for the match at 5-4 in the decider and 30-0 up.
1745: "Re 1728, I'd sit 500 GCSEs for a chance to play at Roland Garros!" From James in Southampton, via text on 81111
1742: Hmmm, I've never heard of the mountain/polar bear combo before - but it certainly sounds impressive. And any polar bear would be happy with a forehand like Del Potro's - it digs him out of a smidge of trouble at 15-30 and draws a couple more errors out of Tsonga to see the Argentine hold. DP is just too consistent at the moment, much to the frustration of the crowd on Philippe Chatrier.
1736: "Del Potro is my favourite player. Taller than a mountain, stronger than a polar bear. And I'm risking getting fired to watch this. Vamos!" From anon, via text on 81111
1731: Jankovic and Cirstea are still with serve in the decider over on Suzanne Lenglen - the former world number one cannot shake the teenager at the moment. Meanwhile, Tsonga is finding it increasingly difficult to hold serve, but he's still clinging on to this...
BBC Sport's Mark Petchey on the Red Button: "Tsonga hasn't found his 'A' game yet but he still believes he can win this one."
1728: For those of you out there revising, spare a thought for Laura Robson who is doing that AND playing at Roland Garros too. The 15-year-old has lined up a British school in Paris if she has to sit her two GCSEs during the girls' singles tournament. Now that is multi-tasking...
1724: The Paris crowd try to lift Tsonga again at 30-all on his serve and they get their wish. A bruising rally ends with Del Potro putting a backhand long from mid-court and Tsonga eventually holds. Just. You sense he is on the brink here though, even at 2-1 up...as Mark Petchey says on the Red Button, "he just needs to grind this one out". That will be easier said than done, though. Del Potro knows he is not far away from the last eight.
1720: (Re 1634) "To be honest I nearly didn't say that last part about Fed as I thought it might be a bit harsh. However, I would much rather someone else won the French Open...hopefully Murray" From J, via text on 81111
1717: Ooof. Jankovic ended up with a bagel in that second set against Cirstea...but she's off the mark in the decider which is 1-1 and with serve. I don't know much about Cirstea to be honest, other than being a decent junior she has not done very much before now - if you know more, please tell me, quickly, and I will claim your facts as my own.
1709: "Our feeling in the commentary box is that this hasn't been the greatest match," Sam Smith says on the Red Button about Tsonga-Del Potro. The Frenchman is trying to rouse himself but, if he is going to get going, he needs to start quickly.
1706: That third set was a bit of a disaster for Tsonga - he has just lost it 6-1. On the Red Button, Sam Smith and John Lloyd "cannot see anyway back for him now". "That was awful," adds Lloyd...I'm inclined to agree.
1659: "(Re 1634) J - what do you mean 'dont let Fed get the Grand Slam'?? Why not?! I hope you never win a Grand Slam!" From Chris in St Albans via text on 81111
1657: Not sure what has happened to Jelena Jankovic over on Suzanne Lenglen but she has fallen apart. Completely. Sorana Cirstea is a set down but is now 5-0 up in the second - impressive for an 18-year-old who had never gone beyond the second round at a Grand Slam until she got to Paris.
1654: Oh dear. Tsonga is mixing brilliance with basic errors - saving one break point with a thudding second serve but gifting Del Potro another straight away by shanking his next forehand about three miles up into the air. The Frenchman attacks on the next point too but puts a half-volley into the net and the Bumble Bee is buzzing again - now a break up at 3-0 in the third set.
1652: "Is it me or does Del Boy look like one of the kids from Fame? He looks like he got dressed in the 80s." From Mark, watching online at work in Brighton, via text on 81111
For those of you watching in black and white, or more probably not able to watch at all - Del (Boy) Potro is still going for the Bumble Bee look - Black, white and yellow stripes...but no little wings.
1645: As I said at 1628, fresh air is over-rated. Yesterday was meant to be my day off from the tennis but things didn't quite work out like that, thanks to Mr Murray and then Mr Soderling. It may well have been the hottest day of the year in the UK but that wasn't enough to get me to leave the house, or more specifically the sofa. And this sun is bound to last all summer anyhow isn't it. Isn't it?
1638: Wowsers! That's got the French crowd on their feet...some thumping Tsonga groundstrokes give him two set points at 6-4 and, although he shanks the first one from a Del Potro serve, he is in at the net with a trademark airbourne smash to put away the second and level the match, in some style too. I'm told Tsonga has never come back from two sets down to win a match so he needed that big-time. Game on.
1634: "I don't see these two beating Fed. It's gonna have to be Roddick or Murray, they are the ones to do it in my view. Don't let him get the Grand Slam!" From J, via text on 81111
1632: Over on Court Suzanne Lenglen, Jankovic has just taken the first set 6-3 against Romanian teenager Sorana Cirstea. Tsonga and Del Potro are locked together at 3-3 in the tie-break. Still anybody's set...
1628: Well, Piers has nipped out for some fresh air (over-rated in my opinion) so you're stuck with me while we see whether Tsonga can lift himself again. He's just flirted with complete disaster, actually, but managed to save a break point this time. That might have been curtains...instead, we're in a tie-break.
By Piers Newbery
1620: Tsonga plays a poor, poor game when serving for the set, making two bad errors and a double-fault to give the game to Del Potro. The Argentine will serve at 5-4 down in the second set. And talking of socks, I can reveal that Andy Roddick will be wearing hand-washed socks against Gael Monfils this afternoon because the laundry was closed yesterday. The American provided photographic evidence of his domestic skills on a popular social networking site. Lovely.
1617: "To be honest, my expectations aren't that high. I'm just going match by match and see how it goes. I do like clay but obviously my game suits a faster surface. I'm trying to change my game to suit clay more. But I don't like what it does to my socks." British junior Laura Robson
1614: Tommy Haas on the break point he had at two sets and 4-3 up, before losing to Roger Federer in five sets: "It was very close. It goes through your head that you could have served for the match. I wanted to play a good return, not too deep, but he hit the winner. You have to tip your hat to him. He went for it. It was too good and he got his reward."
1610: "Just cancelled my meeting tomorrow afternoon so I can keep up with the Murray match - do u think that is a sackable offence?" From Sarah, London, via text on 81111
1608: Tsonga v Del Potro hasn't really caught fire yet, but the Frenchman is working his way into it with some huge forehands. Tsonga earns a break point and Del Potro double-faults, rather surprisingly. Tsonga leads 4-2 in the second. Cristea has slowed Jankovic a little but the Serb still leads 3-1.
1600: "Re 15.53: i believe he was but got voted off for choosing the wrong tsonga." From Rich, Leamington spa, via text on 81111
1600: BREAKING NEWS: Andy Murray v Fernando Gonzalez is scheduled second on Tuesday after Safina v Azarenka, which begins on Chatrier at 1300 BST.
1557: Jankovic has leapt out to a 3-0 lead over Cristea on Lenglen. Meanwhile, a bit more from Roger Federer after his five-set win over Tommy Haas: "Tommy played a great match, I struggled to get into the encounter. He was serving very well, first serve, second serve, I really had trouble returning. I just needed for him to play a bad game."
1553: "Was del potro on britain's got talent on sat?" Chris from very hot computer in east lothian via text on 81111
1550: Tsonga stops the rot with a decent service game at the start of the second set but Del Potro responds for 1-1. I don't know if anyone's mentioned it but Andy Murray is still alive and well in the top half of the draw and ready to take on Fernando Gonzalez in the quarter-finals. The Scot has a 1-1 record against the hard-hitting Chilean and says, "He's very unpredictable, which makes it tough to play against him. I have to play a very consistent match and keep the ball deep. You don't want to leave the ball in the middle of the court against him." That will be live on the Red Button and website streaming (UK only), we'll let you know when as soon as we find out. Promise.
1539: Del Potro works his way to set point and calmly smacks down an ace for 6-1. He's looking very, very good.
1535: Del Potro assumes total control of the first set on Chatrier as he breaks again to lead 5-1 against Tsonga. Next up on Lenglen is Jelena Jankovic v Sorana Cirstea.
1531: "Juan 'the man' del potro is for me THE most improved player on the tour. He hasnt dropped a single set all tournament as yet and I think Tsonga will be swept aside today. Going for a bold 3-0 prediction!" From Arran, leeds, via text on 81111
1531: "I went into my biology exam with roger 2-0 down and I spent the whole exam thinking about he was going lose. I could barely concentrate on my exam paper. Although I have now probably failed my exam I am so relieved roger won!" Shreya from London via text
1528: Tsonga and Del Potro are playing for the right to face Tommy Robredo after the Spaniard completes a 6-4 5-7 7-6 (7-4) 6-2 win over Philpp Kohlschreiber.
1527: Tsonga goes for a wildly optimistic drop shot at 30-30 and finds the net, but the Frenchman plays a great rally to save break point and holds on. Del Potro leads 3-1. These two have met twice before, with Del Potro winning both in tight encounters on hard courts.
1523: Del Potro is doing a good job of silencing the Chatrier crowd as he moves 3-0 clear. Meanwhile, Roger Federer says Haas's failure to convert a break point at 4-3 in the third set was crucial. "I felt that it could be the turning point, it was an incredibly important moment. I was really relieved after that. I was playing badly at the start and my shots weren't finding the target."
1518: Robredo leads by two sets to one and has a golden chance on break point at 3-2, but he hits a mid-court forehand onto the tape. Kohlschreiber fails to take the escape route offered to him though and nets a volley on a second break point. Robredo leads 4-2. And back on Chatrier, Del Potro breaks for 2-0.
1514: Del Potro holds his opening service game to love. The Argentine fifth seed is sticking with the 'bumble bee' look which has taken him this far.
1510: We have had an avalanche of responses to Serena's comments, one or two of which I could actually publish, but to summarise, it seems there is some disagreement with her thesis that women's tennis is better than men's. And apparently, I am anti-French for not liking synth poppers Air, or being consumed by emotion at the retirement of Fabrice Santoro. I can assure you, a list of reasons why I like France would be considerably longer - cheese and Vannessa Paradis spring to mind for starters. And in tennis terms there's Tsonga and Monfils, speaking of which....
1504: Tsonga looks to the sky and punches the air as he walks onto Chatrier - feisty. The home crowd have a big day ahead, with Tsonga in action now and Monfils up against Roddick later.
1502: "Serena needs to let us know when the shuttle lands." From CoronaKing Leicester via text
1458: Robredo has nabbed the third set tie-break to lead Kohlschreiber by two sets to one. Meanwhile, the groundstaff are sweeping and watering the court on Chatrier as we await the arrival of Del Potro and Tsonga.
1450: Oh dear, Fabrice is welling up a bit and I now feel like a heartless oaf. Let's cheer ourselves up with some classic Serena Williams post-match thoughts: "Women's tennis is better than men's tennis, there's no comparison. I'm on the tour, great personalities like Jelena are on the tour. It's way cattier, so it's better to watch. Women are just cattier in general. We're so passionate about whatever we do, ladies just are, and maybe we have more passion and that's what makes it so intense. It's just really exciting." Anybody got any thoughts on that little lot?
1446: Next up on Chatrier - and the Red Button and website streaming (UK only) - is another potential cracker, with fifth seed Juan Martin del Potro up against Jo-Wilfried Tsonga. Before that, the on-court announcer is giving someone the most enormous build-up. Who will it be? Agassi, Borg, Lendl.... no. it's Fabrice Santoro. Nice bloke, interesting style, but am I the only one who can cope with the prospect of a post-Santoro tennis world?
1442: "That was a fantastic last game. Well played Federer, commiserations to Tommy Haas. I guess there was only room for one shock in the 4th round." From jimthree60 on 606
1441: "What an exciting match! Federer has just got stronger as the match has gone on. Dropping the first two sets done him some good!" From Rhi via text on 81111
1438: "Federer came through on the big points and what a gutsy performance," says John Lloyd on the Red Button. It does not get any easier for the Swiss, who will face Gael Monfils or Andy Roddick in the last eight.
1436: Chatrier turns into a Federer-appreciation-zone, with huge cheers as the Swiss gets to 30-0. Haas gets a decent hand when he wins a brilliant point for 30-30, bringing Federer in and swiping away a forehand winner. The German then repeats the trick to earn a break point, but Federer gets out of trouble with a drive-volley. Haas saves a first match point with a sizzling pass but can do nothing about the second, and Federer leaps into the air in celebration.
1436: ROGER FEDERER BEATS TOMMY HAAS 6-7 (4-7) 5-7 6-4 6-0 6-2
1430: Girls' top seed Laura Robson beats Karina Pimkina 2-6 6-3 6-3.
1428: Things are looking good for the world number two, he steps things up to get the double break and Federer will serve for the match at 5-2 in the fifth. He's well and truly pumped now. Robredo and Kohlschreiber are one-set all and 4-4 on Lenglen. Heather Watson loses 7-5 6-4 to Gracia Radovanovic.
1426: Russian industrialisation? Blimey. Federer wallops down an ace for a love-service game and the locals go wild. He leads 4-2 in the fifth.
1424: "Too exciting... Just got back to a computer after agonising revision lesson on russian industrialisation, thought it would be all over by now but Federer's turning into the comeback king..go roger!" From Elena via text
1423: After the nightmare of the third and fourth sets Haas appears to be going well, but three straight errors take Federer to break point at 30-40. Haas steps in and smacks away a forehand winner to save it, but cannot control a backhand in the next rally and it's break point two for Federer.... and Haas goes long with a forehand. Federer breaks to lead 3-2.
1417: "Ok, this is killing me!!! The tension is unreal! Come on rog!" From Ged, a bar in sydney, via text on 81111
1417: Federer opens up with a sublime backhand pass down the line, and he edges through another service game to 30. It's 2-2 in the fifth.
1413: Haas wins four straight points to move 2-1 up in the fifth against Federer. Heather Watson breaks when Radovanovic serves for the match and trails 7-5 5-4, Laura Robson leads by a break in the second set.
1410: More nervous moments for Federer fans when Haas belts a forehand winner to move 0-30 clear, but the Swiss digs deep with a couple of big serves and a deft drop volley to earn game point, and seals it with another big serve - 1-1 in the fifth.
1408: "Watching the match praying for your guy to get it together is possibly the most frustrating feeling in the world! After 2 sets of agony for myself i feel for the haas supporters out there..well not really, go roger!" From Chris, st albans, via text on 81111
1407: "Really impressive serving," says John Lloyd on the Red Button as Haas opens with a love hold.
1405: OK, both men have been for a 'comfort break' and so have I, so we're all 'comfortable', right? Haas to serve first in the fifth.
1402: Federer wraps up a 6-0 love set and we go into the fifth. Haas did not put much effort in towards the end there so hard to judge how he's doing physically, but he's lost nine straight games and heads off for a 'comfort break'. Me too.
1359: Apologies for the error in my last update, your compassion, as ever, overwhelms me. To clarify, Federer is still playing Haas and he is serving at 5-0 in the fourth set. Press F5 and it will be like it never happened.
1357: "I am about to bite my fingers off! Must have pressed refresh a 100 times in the last minute. P.S come on fed. You can't lose. Please YOU HAVE TO WIN! - At Work screaming my backside off." From Shaz, oxford, via text on 81111
1357: "In my lessons i get told off for being too noisey: a de brito." From James via text
1354: Federer eases 4-0 clear of Haas and we're set for a decider. Robson levels at one set all against Pimkina, Kohlschreiber does the same against Robredo.
1351: I'm dusting off the tantrum graphic as Haas misses another sitter of a volley and then nets a forehand to go 0-40 down. The German battles back to deuce, double-faults and then sees Federer play a winning drop-shot return he probably didn't mean. Federer gets the double-break for 3-0 in the fourth set. Robson is 5-3 and serving in the second set, Watson is 1-3 in her second set.
1347: Federer consolidates the break impressively and leads 2-0 in the fourth. "Allez, Roger!" shouts one gentleman.
1345: Haas is in trouble at 15-30, finds a big serve but then plays a horror volley in a point Federer had given up on. The German pays for it when Federer gets him out of position and Haas nets a backhand. A break of serve for Federer at 1-0 in the fourth set.
1339: Federer takes the third set 6-4 and the crowd on Chatrier roar their approval. Get the teas in, we could be here for a while. Robredo leads by a set and 5-5 against Kohlschreiber, and Watson drops the first set 7-5 against Radovanovic.
1336: Federer goes for too much on a couple of forehands but a double-fault from Haas takes it to deuce, and the German then pulls a forehand into the tramlines. Break point for Federer.....and we get one of the rallies of the tournament - Federer throws up a defensive lob, Haas turns and chases it down, the German comes to the net and then sends a volley long. Federer breaks to move 5-4 clear and will serve for the set.
1329: Federer has been impressively calm so far but we get the first fist pump of the day when he plays a heavy forehand to go 30-15 up. However, two very wild efforts off the same wing follow and it's break point for Haas..... Federer runs around his backhand, everyone holds their breath, and he smacks a magnificent winner! A big serve and a Haas error follow, and Federer screams in delight. It's 4-4.
1323: Now it's Haas's turn to feel the pressure at 30-30, but Federer swats a very makeable forehand into the net and he looks furious. He then bunts a forehand over the baseline and Haas leads 4-3 in the third.
1320: Things look a bit dicey for Federer at 30-30, second serve, but Haas cannot put the pressure on and the Swiss comes through - 3-3. Regarding the rankings possibilities, the ATP line is "Federer could lose his number two ranking to Murray but Murray must reach at least the semi-finals and finish one round ahead of Federer."
1317: Robson drops the first set 6-2 against Pimkina, Heather Watson is on serve at 5-5 against Radovanovic. For those asking about TV coverage of the juniors, there are no television cameras on the courts the juniors play on and the host broadcasters don't plan on covering the junior events. In fact, Wimbledon is the only Grand Slam where you do get some coverage of the junior tournaments.
1315: Haas looks a solid as a rock right now and leads 3-2 on serve. There are lots of people asking whether Murray can overtake Federer as number two in the world if the Swiss loses. I do not know, but by crikey I will find out.
1312: A solid enough hold from Federer levels it up at 2-2 in the third. "I can see tomorrow's headlines now, Neil: 'Federer dumped on his Haas'," says Jonathan Overend on 5live Sports Extra. Times correspondent Neil Harman responds: "Well I work for a paper with slightly classier headlines than that, Jonathan."
1308: Haas holds serve to 15, sealing it with a nice backhand pass, and he leads 2-1 in the third. A lot of people are now asking Cameron in Kendal (see 1141 entry) for the lottery numbers.
1304: Robredo takes the first set against Kohlschreiber and British girls Robson and Watson are currently trailing in their matches early on. It's all eyes on Chatrier for now though, as Haas and Federer hold their opening service games for 1-1.
1300: "The dream is still alive for Roger Federer but it's hanging by a thread," says Mark Petchey on the Red Button. "Is this his Andre Agassi moment?" (The American came back from two sets down to beat Andrei Medvedev in the 1999 final).
1257: Real drama on Chatrier as Federer nets a backhand on the run to slip 30-40 and set-point down, but Haas plays a woeful chipped return which floats long. Federer then blazes a forehand miles wide and it's set point number two.... a long rally and Federer hammers a forehand into the net. Haas leads by two sets to love!
1254: The Wimbledon Mole has a breathtakingly original plan for 2009 - basically, flirt with the promotions girls at the tube station, grab any free samples on offer, a quick flick through the tabloids and attach oneself limpet-like to Greg 'Ruser' Rusedski for a fortnight. Greg, you have been warned.
1251: Haas moves 6-5 clear and has guaranteed himself at least another tie-break.
1245: Typical, you look away for five minutes in a 10-hour day and something significant happens. Haas appears to have broken back and now leads by a set and 5-4. What in the name of Philippe Chatrier is going on out there this week?
1236: There is one Spaniard still going strong, good old Tommy Robredo, and he leads Philipp Kohlschreiber 3-1. Britain's Laura Robson is about to start on Court Six, Heather Watson is out on Court Seven, and exciting news on a personal front as I believe the Wimbledon mole is burrowing his/her way in my direction for a pre-Wimbledon chat. Exciting times.
1230: That's right, Keith, Chatrier=Centre Court, Lenglen=Number One Court, Court Two=Er, Court Two. Incidentally, we have a new Court Two at Wimbledon this year, and there are plans for a new Court Three.
1228: "Piers, is Court Philippe Chatrier the equivalent of Centre Court please?" From Keith, suddenly interested now Nadal is out, on a train to Londres via text
1225: Haas goes long to give Federer a break point and the Swiss takes it with a backhand pass. There is a sense of relief from the crowd, who are definitely pulling for Federer to finally win at Roland Garros. He leads 2-1 in the second set.
1219: At least one person is, Luke.
1217: "Is anyone else chuckling immaturely at the french umpire's pronounciation of 'Haas'?" From Luke, Liverpool, via text on 81111
1217: "I'm afraid Sina can't be any relation to Tommy. Tommy has two sisters, but they are called Sabine and Karin (according to a popular wiki-style website)." From Armi89 on 606
1216: And there we have it, Haas sees his lead cut from 5-4 to 5-2 but remains calm and serves out for the set. "He can't win this, can he? Surely? We said that yesterday," muses John Lloyd on the Red Button.
1213: After hanging on for 12 games, Haas inevitably takes charge of the tie-break and changes round 4-2 up.
1212: "Thanks to live commentary I'm doing a Wozniak in the office. Not working hard and performing terribly!" From Ian, southampton, via text on 81111
1212: "I'm quite happy doing a Bjorn Borg these days. I passed my exams years ago and now i offer commentary on those in the exam court today." From Paddy via text
1212: "I'm planning on doing a Nadal in my exam today! Oh, wait..." From Matt, London, via text
1209: Haas belts a backhand winner to force the tie-break and the German finally gets a point on the Federer serve to go 1-0 up..
1207: "Can you believe it; I've just been offered courtside Chatrier tickets for Friday mais zut alors, I've got exams all day. Je suis en colÉre..." From Chloe, Plymouth, via text on 81111
1205: That's a beauty and gets me spluttering my orange juice - a sweet backhand down the line helps Federer to a sixth consecutive love hold. Magnifique. He still hasn't broken Haas though and the German must hold to force a tie-break. There is a Sina Haas of Germany currently playing in the girls' singles. Could it be...?
1201: Federer completes his fifth straight love-service game - that's 20 points in a row - and he leads 5-4. "Haas has competed well on his own serve and it's a very good match," says Times correspondent Neil Harman on 5live Sports Extra. "There's definitely a strong breeze out there though."
1159: "Re 1056: I'm planning on doing a Davydenko in my exam today - just enough to pass comfortably, nothing spectacular!" From jonny on 606
1157: Next up on Court Suzanne Lenglen is Tommy Robredo v Philipp Kohlschreiber, conqueror of Novak Djokovic. After her swift demise against Serena Williams, Aleksandra Wozniak says: "When you want to win really badly and it's your first time on Court Philippe Chatrier, emotions get involved. You get tight and you can't play your game and it's tough."
1152: Seventh seed Svetlana Kuznetsova beats 12th seed Agnieszka Radwanska 6-4 1-6 6-1 and will face Serena Williams in the quarter-finals.
1148: A Laura Robson update - the first match on Court Six is on into a deciding set so probably half an hour or so to go. Heather Watson, the 13th seed, plays France's Gracia Radovanovic in the third match on Court Seven. Federer gets a bit lucky with a mishit backhand pass that drops in for break point, but Haas saves it. And I've gone way too early with my lunch.
1144: I think..... non, monsieur. Federer plays a deadly forehand drop shot to take the game and move 3-2 up. Haas gesticulates wildly towards the sky about something or other. You never know with Tommy. Kuznetsova is a game away now.
1141: "Haas to win in four sets, 7:6 3:6 7:5 6:4. What ya think piers?" From cameron in kendal via text on 81111
1135: Kuznetsova holds serve to move 3-0 up in the decider against Radwanska. It's been tough going today after an easy passage into round four but the Russian looks on course to meet Serena.
1133: Federer steps in and smacks away a forehand drive-volley to hold his opening game, and you get the feeling he's happy to be facing Haas today. "It will be nice to watch while it lasts but I can't really see Haas causing an upset here," says John Lloyd on the Red Button.
1130: "Federer probably views this as the best chance he's ever going to have to claim the French Open title. But, with Nadal out, the other men left in the draw will also be thinking the same thing - not least Soderling, who (if he can refrain from getting giddy) must believe he's in with as good a chance as anybody, having already ousted the King of Clay." From Sabatini on 606
1126: "I'm sitting here in the Phillipe Chatrier Court and the atmopshere is amazing! The crowd is very eager to see if Federer can claim his first trophy at Roland Garros." From Zane, currently in Paris, via text on 81111
1123: Federer and Haas are out on Chatrier, lazily knocking up in the sunshine. These two have had some decent matches in the past but Rog generally prevails, eight times out of 10 in fact. And he hasn't lost to the German since Australia in 2002. This is the first time they have met on clay though, and after yesterday.. who knows?
1118: I seem to remember quite liking Moon Safari when it came out about 10 years ago, but after a week of Red Button interludes the sound of ambient French synth pop is making me want to smash something. Radwanska takes the second set against Kuznetsova 6-1 - interesting.
1109: Second seed Serena Williams beats Aleksandra Wozniak 6-1 6-2 to reach the quarter-finals. Very impressive stuff, and it means the Red Button and website streaming (UK only) coverage will continue with Roger Federer v Tommy Haas in a few moments.
1107: Reaction to Nadal's defeat continues to come in. Six-time winner Bjorn Borg tells Sweden's Expressen newspaper: "If you can beat Nadal on clay in Paris then you can beat anybody. I think that Soderling can now win the French Open." And a relieved Nikolay Davydenko says: "Against Soderling I don't need to run so much and play long rallies. There will be short points. Not like against Nadal when you have to run 20 minutes for one point and then you are already tired."
1103: Ksenia Kirillova takes the first set against Timea Babos on Court Six. 'Who does what against who?' I hear you say. 'And why?' Well, if Ksenia can bag the next one it will be time for Laura Robson to start her girls' singles campaign. And Wozniack has avoided the slightly dreaded 'double breadstick' by finally breaking Serena - she still trails 4-2 in the second set though. Radwanska is a break up on Kuznetsova in the second.
1059: "Svetlana Kuznetsova wins the first set 6-4. Not a great show but I guess we need the rest after yesterday! Strange Kuznetsova is wearing pink today though, you would have thought most players would avoid pink for the rest of this Slam..." From Diarmuid_Bxl on 606
1057: "How about a safina? Only dropping 5 marks in my chemistry exam on wednesday." From simon in sunny sheffield B-) via text
1056: "Yep, I'm pleased at the lack of Murray talk! I was looking at the draw there and I'd take a Fed v Gonzales final." From Stevo in Ballymena via text
1051: Kuznetsova takes a hard-fought first set 6-4 against Radwanska, meanwhile the Serena demolition job continues as she moves 6-1 3-0 up on Wozniack.
1049: With the known world - and probably parts of the unknown world - still reeling after Nadal's defeat last night, Maria Sharapova continued her fairly remarkable run with another three-set win, this time over Li Na. The Russian, playing her fist Grand Slam since Wimbledon after nine moths of shoulder hell, showed real grit to win 6-4 in the third. "I think expectations are just words, and so is pressure," said the 22-year-old afterwards. "I'm here to get the job done, and my job isn't done."
1043: " When I saw Rafa faltering yesterday, I put a cheeky £10 on Fed at 3/1! Come on son, get the career slam!" From Alex, Exeter, via text on 81111
1043: "Nevermind doing a soderling, I would take a serena williams. Complete and utter anihilation of the opening set/history paper 1." From Sam in london via text
1039: Serena wraps up the first set 6-1 against Wozniack in just 23 minutes, finishing it off with a vicious smash.
1037: Barely a mention of Andy Murray so far, which will please some and infuriate others. He was on great form yesterday, beating Marin Cilic in straight sets, and it's Fernando Gonzalez next up. That will be on the Red Button and website streaming (UK only), obviously. I'll let you know as soon as we have some schedule information later on today.
1033: Serena is on top form today, leading 4-1, and poor old Wozniack is having a miserable time. The winner of this one will pay Kuznetsova or Radwanska next, the Russian leading 4-3 with a break. It's a bumper line-up today but, personally, Del Potro v Tsonga is the one I'm really looking forward to. Both men must feel they can win it now.
1030: "I've taken a £2 punt on Gael Monfils at 37-1. I really hope Fed does it but them odds were just too tempting." From Rob, Oldham, via text on 81111
1028: "Made a tidy profit out of rafa yesterday instead of revising oops." From anon via text
1027: "Re 0950. Indeed, lots of students around the country are hoping to pull off a soderling in exams today." From Jamie, Oxford, via text
1025: The big names are not messing around this morning, perhaps spooked by losing not only Nadal but women's champion Ana Ivanovic yesterday. Serena is 3-0 up and Kuznetsova 4-2 in front.
1021: Still on Rafagate and it's nice to see he and Soderling are getting along better than at Wimbledon a couple of years ago. Nadal won a third-round match that was played over five days because of terrible weather, and said afterwards: "He's very strange. I say hello to him seven times to his face, he never answers. He hits a lucky shot, he does not wave. I thought it was me, but I asked around the locker room and almost nobody has anything nice to say about him. If I fall down, he says nothing. He touches his backside, grabs his pants, makes fun of me - very unprofessional."
1016: After an inordinately long warm-up we're ready for some action, and Serena serves first against Wozniack. On Court Suzanne Lenglen we have seventh seed Svetlana Kuznetsova up against 12th seed Agnieszka Radwanska.
1013: If you get the chance, have a listen to Nadal's press conference from yesterday evening. While my peers attempt to find the secret to the defeat, the man himself is pure class. "Defeats never make you grow but you also realise how difficult what I achieved up until now was," he said. "You need a defeat to give value to your victories."
1009: "Probably won't even see Federer's match - got revision for my exam this afternoon! Mind you, didn't stop me from watching the third and fourth set of Nadal's match yesterday: amazing!" From AlexR4444 on 606
1007: So, Rafa.... Firstly, I think we all owe Elena Dementieva an apology. Who among us did not scoff on Saturday when the Russian said: "He actually looks a little bit tired to me. I think it's going to be a tough challenge for him to win this time, actually." Any lottery numbers, Elena?
1004: It's another beautiful day in Paris and Court Philippe Chatrier is surprisingly quite full, bearing in mind the time of the day. First up is second seed Serena, who is still going despite some tough matches, against 24th seed Aleksandra Wozniak of Canada. I would say this looks pretty straightforward for the American... but I won't.
1000: Andy Murray might be enjoying a day off but there is British interest today as top seed Laura Robson begins her campaign in the girls' singles against Russia's Karina Pimkina in the second match on Court Six - I'll keep you up to date with that one.
0953: We will reflect more on Rafa's demise but this already thrilling tournament has a whole new edge now, and today's line-up is a belter. The provisional schedule for the Red Button and website streaming (UK only) is to stick with Court Philippe Chatrier from 1000 BST for Serena Williams v Aleksandra Wozniak, followed by Roger Federer v Tommy Haas and then Juan Martin del Potro v Jo-Wilfried Tsonga, before switching over to Court Suzanne Lenglen for Gael Monfils v Andy Roddick. And we are joined in the second week by live coverage every day from 1000 BST on BBC Radio 5live Sports Extra.
0950: Robin..... Soderling. Not Roger Federer, Andy Murray or Novak Djokovic. Not even a Juan Martin del Potro, Jo-Wilfried Tsonga or Gael Monfils. From this day forward, when a man (or woman) overcomes seemingly insurmountable odds, dreams the impossible dream, fights the unfightable foe etc, let it be known as 'doing a Soderling'. And in the words of the late, great Brian Moore, "It's up for grabs now!"
