Round-up - Day two at the Open (UK only)
World number one Tiger Woods missed the cut in the Open for the first time in his career as Tom Watson continued to roll back the years at Turnberry.
Woods shot a 74 to finish on five over, 10 shots adrift of 59-year-old Watson, who claimed a share of the halfway lead with fellow American Steve Marino.
Mark Calcavecchia lies one shot behind the joint leaders, with England's Ross Fisher in a group on three under.
Ben Curtis, the 2003 Open winner, and Colin Montgomerie also missed the cut.
But defending champion Padraig Harrington still has a chance of making it a hat-trick of Open titles.
The Irishman carded a four-over-par 74 in difficult, windy conditions for a three-over aggregate of 143, eight strokes off the lead.
The spirits are on my side - Watson
"I wasn't thinking about making the cut," he said. "I was thinking I'm eight shots behind. That's not insurmountable on the weekend on a links golf course, especially like this."
It is only the sixth time that Woods has failed to make the halfway mark in his professional career and only the second time in a major.
The 33-year-old missed out at the 2006 US Open following the death of his father.
Woods, the pre-tournament favourite, dropped seven shots in six holes either side of the turn, including double-bogeys at 10 and 13.
"No doubt I'm frustrated, it just didn't happen for me," he said. "I played three holes very poorly.
"Up until the 7th I was doing fine, I was where I needed to be, but bogey, bogey, double bogey got me going the wrong way.
"Until 8 I felt I was in there for the tournament. I thought if I could finish under par I might finish the day in the top 10. But I didn't, I went the other way.
"I birdied two of the last four and I think that's not going to be enough. You can't make mistakes and expect to not only make the cut but also try and win a championship."
Tiger frustrated at poor performance
Woods, who shot 71 on day one, made crucial birdies at 16 and 17 and got up and down from off the green to save par at 18, but it was not enough to keep him in the tournament.
After a sunny and benign opening day, the players had to contend with windy and wet weather on day two - with only seven managing to shoot under par.
Watson went into the second round just one shot behind overnight leader Miguel Angel Jimenez but a horrid front nine seemed to end the prospect of a fairytale challenge.
After a birdie at the 1st, the five-time Open champion then went on a run of five bogeys in six holes as the conditions wreaked havoc.
But Watson, who won the second of his five Open titles in the famous 'Duel in the Sun' championship at Turnberry in 1977, stopped the rot with birdies at 9 and 11.
The best was yet to come, however, as superb 60ft putts at the 16th and the 18th gave him a share of the lead.
"I'm still emotional after that," admitted Watson, who won the last of his eight majors in 1983. "It's as if the spirits are on my side and I wouldn't be here if I didn't think I'd win it.
"The front nine is the toughest part of the golf course but I told myself that if I played smart coming home I would make some birdies.
"On the front nine the only thing I was trying to do was play one shot at a time and trying to get the birdie that would stem the tide. I did that at 9."
Marino, playing in his maiden Open, was a late call-up to the championship field and only played his first round of links golf this week.
But he defied the inclement conditions to post a stunning 68, the second lowest score of the day, which included four birdies and an eagle.
The 29-year-old produced some of the shots of the round as well, chipping in with a sand wedge from 116 yards at the 3rd and holing from the bunker at the par-three 6th.
"I've really enjoyed myself here, I'm having a blast," said Marino. "I love the challenge that this course presents. You have to stay patient and stay positive.
"I'm looking forward to playing golf here the next few days."

Calcavecchia, 49, who won the Open at Troon in 1989, carded four birdies in his 69 and admitted he was happy just to make the cut.
"I'm usually choking so bad coming down the last few holes on Friday because I want to play the weekend," said the American.
Fisher, who finished fifth at this year's US Open, leads the British challenge thanks to a 68 that included a run of three birdies in the closing four holes.
But the 28-year-old reiterated his intention to quit the tournament if his expectant wife Jo started to go into labour.
"I'd love to be here for all four days but obviously my wife comes first," said Fisher. "If she were to go into labour later on this evening or tomorrow I've got no choice.
"I want to be there. It's going to be a great experience and one that I don't want to miss."
With Fisher are two-time US Open champion Retief Goosen (70), 2000 Masters winner Vijay Singh (70) and Japan's Kenichi Kuboya (72).
Jimenez is also on three under after bouncing back from a poor front nine for a second-round 73.
England's Lee Westwood and the big-hitting American JB Holmes are in the group on two under after both carded rounds of 70.
World number five Sergio Garcia, who has a fine record in the Open over recent years, carded a 69 to join the likes of Jim Furyk and Argentine Masters champion Angel Cabrera on one under.
Ireland's Padraig Harrington, who is chasing a hat-trick of Open titles, is on three over after a 74 but insisted that eight shots "was not insurmountable on a links golf course".
Northern Ireland star Rory McIlroy (74) is on the same total, one stroke ahead of world number three Paul Casey (76) - who made the cut by a shot.
Montgomerie was just the other side of the cut line to cap a traumatic week in which he was caught up in a public spat with Sandy Lyle.
Curtis had been one off the lead after round one but collapsed spectacularly on the second day, carding eight bogeys and two doubles on the way to a 10-over-par 80.
Another player to go home early was the hotly-tipped Ian Poulter, who added a 79 to his opening 75.
"I could have had a set of spades in my bag this week and I still wouldn't have found the middle of the greens," he said.
