Mother nature has not been kind to the US Open this year, as heavy rain and fierce winds have forced some matches to be postponed.
On the men's side Novak Djokovic and David Ferrer were able to begin their semifinal match on Saturday, but poor weather forced the match to be completed Sunday morning.
Who will win the women's final?
The women's final was originally scheduled for Saturday, but intense rain forced the match to be moved to Sunday. When the match is finally able to get underway, tennis fans will be treated to a spectacular battle between two of the sport's best players.
Williams and Azarenka have each won a Grand Slam tournament this season and have arguably been the two best players on the women's tour in 2012. Williams still hasn't lost a set at the US Open, and while Azarenka has lost two of them, she has played tougher competition on the road to the final. She needed to beat No. 7 Samantha Stosur and No. 3 Maria Sharapova to earn a match with Williams.
When Ferrer resumes his match with Djokovic on Sunday morning, he will have a 5-2 first set lead, and will be in prime position to take an early advantage.
It will be interesting to see how he responds when the pressure increases. Djokovic has made some incredible comebacks in his Grand Slam career, including an amazing one in the semifinal of last year's tournament against Roger Federer in 2011.
If Ferrer can continue to play well and stay mentally focused, he will advance to the first Grand Slam final of his career. Andy Murray has already advanced to the men's final.
Let's look at all the information you need to watch Sunday's exciting tennis from the US Open.
