U.S. Open: Serena Williams upset in finals by Samantha Stosur

Serena Williams suffered another temper meltdown at the U.S. Open and then a momentous loss Sunday in the women's final of the U.S. Open.

Ninth-seeded Samantha Stosur of Australia won her first major championship with a 6-2, 6-3 win over 28th-seeded Williams on Sunday on Arthur Ashe Stadium. If the seedings made Stosur the favorite, Williams, who was already a 13-time major winner, was the heavy favorite.

But in the first game of the second set, as Williams hit what was about to be a definitive forehand winner to save a break point, Williams bellowed just before the ball landed. Chair umpire Eva Asderaki of Greece called Williams for a violation and the point was awarded to Stosur.

It also meant the game went to Stosur and as boos filled Arthur Ashe Stadium, Williams had a contentious discussion with chair umpire Asderaki that included Williams saying,"If you ever see me walking down the hall, look the other way."

The last time Williams played at the Open, in 2009, she lost to Kim Clijsters in the semifinals, a match that ended with a controversial foot fault called on Williams that caused Williams to burst into an obscenity-laden tirade that included a threat of shoving a racket down the throat of the lineswoman who made the call. It also resulted in a penalty point that ended the match in Clijsters' favor.

Sunday, after the code violation was called, Serena seemed to say, "I get a code violation for this? I express who I am. We're in America last I checked."

Stosur seemed momentarily unnerved by the incident and the Ashe crowd booed loudly for almost a minute and Williams came back to win two straight games to take a 2-1 lead from 0-1 down.

But the 27-year-old Stosur never changed expression or quit hitting winners. On her third attempt at match point, Stosur pounded a forehand return winner past Williams to complete the 1 hour, 13-minute win.

Williams was gracious on court during the awards ceremony, saying the point that was given to Stosur didn't matter because Stosur was playing too well anyway.
