The defending women's US Open tennis champion, Kim Clijsters, will play Russia's Vera Zvonereva for the title tomorrow afternoon, after the Belgian defeated Venus Williams 4-6 7-6 6-4 in her semi-final.
Zvonereva upset the top seed Caroline Wozniacki of Denmark 6-4 6-3 to claim her finals spot.
The men's semi-finalists face-off tomorrow morning, and the world number two, Swiss Roger Federer, says he's looking forward to his match against the in-form Serb, Novak Djokovic.
Federer says it's the fourth straight year that they've met at the US Open, and while he's got the better of him in their past three meetings at Flushing Meadows, Djokovic is currently enjoying some great form.
The top men's seed, Rafael Nadal of Spain, will play Russia's Mikhail Youzhny in the other men's semi.
