Sharapova can't bare the sight of another potential unforced error
"If I didn't make those errors, those double-faults, I certainly would have won the match."
After losing 3-6 6-4 7-5 to Melanie Oudin, Maria Sharapova figures out that 21 double faults and 63 unforced errors cost her the match
"I'm still realising I have beaten Maria Sharapova on Arthur Ashe Stadium in the third round of the US Open."
Oudin had better come to terms with her feat before facing Nadia Petrova in round four
"They just told us 'We're switching you to Armstrong (from Arthur Ashe)', and basically that's it. It's very unfair. From my side, I can say, I'm number one player in the world, why did they move me?"
Dinara Safina blames a late switch of courts for unsettling her - so that's why she lost...
"The fact that I was able to make the quarter-finals last year and I was playing just terrible, and didn't make it past the third round this year. That's the thing with sports - there's not always a good reason for it."
Andy Roddick finds it hard reflecting on losing to John Isner in a five-set thriller
"Obviously Andy and I are really good friends off the court. On the court, we're going to lay it all out there. I don't like that he's out of the tournament. I mean, it kind of stinks that we played in the round of 32."
Isner offers a shoulder to cry on for Roddick
"Looking at that match, I don't know who was number four in the world. It was a tough win. For either one it would have been well deserved.
Fourth seed Novak Djokovic survives a scare against American qualifier Jesse Witten - world number 276.
"It gives me some money to keep playing. So now I can afford to keep playing for the rest of the year, at least. I don't know how good I am, so it's good to kind of see that I can play with these guys and I kind of belong a little bit here."
Witten is happy with his $48,000 pay cheque
"I don't have to worry about conserving one shirt. I can just go through them and just throw them in the laundry bag. You get chauffeured around with the cars. Everything is nice here. This is the best tournament in the world. You can't beat this."
Witten on life as a player who was dropped by his clothing sponsor one day before the US Open qualifying event
"Sure, I'm losing sleep, but that's part of it. I make sure on my off day maybe I do get a night where I can sleep in longer or take an afternoon nap. It's working out OK."

"I'm very happy. It was amazing. Second set I was very down. I was not focused. It was terrible. Safina played very well. After that I concentrated on every ball and I won."
