"This is what it's about for me. Not a billion dollars can compare to the feelings I felt in the last two weeks."
Errani, 27, said: "She hit the ball unbelievably strong. She's the kind of player I don't like to play too much, so I just tried to be very focused every point."

"When we had that break I said, 'OK, win or lose, I'm going to go for my shots. I'm going to go for it. This is the only chance I have to win. If I'm going to lose, at least I'm going to do it with dignity.'"

Quotes of the day
"I am OK. It's one match of my career. Don't worry." David Ferrer hides his disappointment at losing to Gilles Simon.
"I never sweat like this in the last 10 years." Gilles Simon describes the testing conditions.
"It was really difficult to time the balls, especially on her ball and her serve. It comes so slow and it kind of floats in the air." Mirjana Lucic-Baroni is among a select few to have been bamboozled by the Sara Errani serve.
"I don't serve very fast," confirmed Errani. "Of course you see that. It's difficult for me. I try to improve my serve, but I have a different kind of serve. I don't try to make winners with my serve. I just try to make kick, make slice, try to change my game."
"I think that's the flood warning. Darn it. If I was only there a little longer." Maria Sharapova responds to phones buzzing all around during her press conference.
Rain stops play
As the skies darkened above New York, phones began to buzz all around Flushing Meadows - "Flash Flood Warning. Avoid Flood Areas".
On Arthur Ashe Stadium, Granollers was interrupted during the set of his life as he led Federer 5-2 when tournament referee Brian Earley called a halt to proceedings.
It proved a wise decision, as minutes later the predicted downpour arrived, leading to the cancellation of the day session.
