New York, Sep 11 (IANS): Serena Williams eliminated top seed Caroline Wozniacki 6-2, 6-4 in the semifinals of the US Open tennis here Saturday night to set up the final showdown against Samantha Stosur.

Williams, out of the sport for almost a year due to a series of injuries, reached her fifth US Open final.

The 28th-seed American, who is aiming for her 14th major title, has reached the final without dropping a set.

The ninth seed Stosur advanced to her first US Open final with remarkably little notice, considering she has already played the longest tiebreaker in women's major tournament history and won the longest women's match time-wise in tournament's history.

Stosur, 27, beat 92nd-ranked Angelique Kerber of Germany, 6-3, 2-6, 6-2 in the first semifinal.

When Williams, 29, was leading 6-2, 1-0, she had whammed and bammed her way to 20 outright winners to none by the 21-year-old Wozniacki, whose signature style is to run down every shot and send it back.

By the end, Williams had 34 winners to only five for Wozniacki, for which made up for the American's 34 unforced errors to 12 from the Dane.

"I want to play on 911, so I am eager to reach the final," Williams was quoted as sayin by Xinhua.

There was a worrisome moment for Williams in the first set. During the changeover after Williams had taken a 4-1 lead with a booming forehand volley, she called for the trainer to tend to her big toe.

Lengthy rain delays during the week and water damage that shut down Louis Armstrong Stadium caused schedulers to put Stosur and Kerber on the smaller court and leave two men's semifinals and the Williams vs. Wozniacki semifinal at Arthur Ashe Stadium which has seating capacity of 23,000.
