US Open Tennis: Serena Williams Proves She Has No Rival in Women's Tennis

Prior to the US Open semifinal match between world No. 1 Caroline Wozniacki and Serena Williams, many tennis fans and analysts believed that this match would decide who was truly the best player in women's tennis.

In her 6-2, 6-4 victory, not only did Williams answer this question, but she did so in convincing fashion, ending Wozniacki's quest to win her first major. 

From the onset of the match, it was apparent that Serena, seeded 28th, had elevated her game to another level and Wozniacki was simply along for the ride. Unleashing 11 powerful aces and 34 winners, she was barely tested by one of the few women standing in the way of her first major title since winning the 2010 Wimbledon crown.

At one point during the second set, Williams had hit 20 winners to Wozniacki's zero, a testament to her dominance of the game's No. 1 player on the night.

On the heels of injury troubles, which sidelined her until June, Williams has truly been rolling on all cylinders this summer as this victory pushed her hard-court record to 18-0.

This match does not mark the first time that Williams' status as the best player on the WTA Tour has been called into question.

In 2009, Dinara Safina—another woman with no major titles—managed to take the the top ranking from Williams, drawing much criticism from the 13-time grand slam champion.

"We all know who the real number one is," Williams stated at a press conference at the 2009 Italian Open. "Quite frankly, I'm the best in the world."

Outside of Williams, the last woman to be ranked No. 1 on the WTA Tour who was also a major champion was Kim Clijsters, who briefly held the top spot for a week in February 2010 before ceding it to Wozniacki.

Next up for Williams is Samantha Stosur, a 27-year-old who defeated unseeded Angelique Kerber of Germany 6-3, 2-6, 6-2 in the other semifinal match to become the first Australian woman to reach the US Open final since 1977.

Though Stosur will be the heavy underdog in the championship match, Williams will no doubt be seeking revenge as she was defeated by Stosur during their last meeting, a three-set thriller in the quarterfinals of the 2010 French Open in which Williams was unable to convert a match point she held.

It will take an extraordinary effort for Stosur to beat Williams if Williams maintains her high level of play, but the world No. 10 is not lacking in confidence.

"I am the underdog but having said that I am going to believe I can do it," the Australian said.

The crowd will no doubt be pulling for Williams to complete her comeback with a victory and Stosur will have her hands full as she tries to play the role of spoiler.
