Serena Williams produced a stunning fightback to win the U.S. Open final against Victoria Azarenka.
Williams was 5-3 down in the deciding set but recovered to take it 7-5 and claim her fourth singles crown at Flushing Meadows.
The victory caps a remarkable two months for Serena which has has also seen her win Wimbledon and Olympic gold.
Williams, who spent a year out of the game with a foot injury in 2011, said: "I don't think about the downs too much. I hope I never think about them as my life continues. But I really think a champion is defined not by their wins but by how they can recover when they fall. I have fallen several times.
"Each time I just get up and I dust myself off and I pray and I'm able to do better or I'm able to get back to the level that I want to be on. So I feel really awesome that I have been able to do that and that I can do that.
"You see great people like Muhammad Ali, who is a complete person I have always looked up to in sports. I just really think that defines a champion.
"Obviously I would have wanted to win easy. But, at the same time, this is more exciting to win because you don't really know what's coming. You don't know what to expect, and then you get it. This is the best feeling I think in tennis.
"To cap off the gold medal and then to come from the gold medal to win US Open is unforgettable. I'm really so excited."
This was the 15th singles Grand Slam title for the 30-year-old and she is now seven behind the all time record held by Steffi Graf.
