With Williams moving slower than usual due to a possible toe injury which bothered her in the semifinals and with Stosur’s forehand at an all time best form, the Australian would win the last 12 points of the first set.

A Stosur forehand down the line winner on set point sent the 27 year old up a set.

Controversy struck in set two with Williams serving down 30-40. After powering a seemingly winning forehand down the line, the 29 year old American shouted “come on” before the ball bounced twice with Stosur still reaching for the ball.

Thus the chair umpire ruled Williams had hindered the Australian and the game was given to Stosur which left Williams down 0-1 in the second set.

Williams had words with the umpire in the following minutes and was given a code violation for verbal abuse. A sampling of Williams’ comments to the chair umpire: “You screwed me before. I hate you. Don‘t look at me.”

Today Williams was fined $2,000 by the US Open for verbal abuse. But hardly something for a player who has won more than $30 million in prize money to worry about.

Williams would recover briefly to lead 3-2 in the second set after holding serve with an ace.

But the day belonged to Stosur as she would end the match on her third matchpoint with an inside out crosscourt forehand return winner.

After the 1 hour 12 minutes long match, Williams laughed and talked with Stosur after refusing to shake hands with the chair umpire.
