Serena Williams and Maria Sharapova will hit the court Friday as both look to gain a berth in the U.S. Open's women's final, highlighting action from Flushing Meadows, N.Y. as the tournament enters its home stretch.
The fourth-ranked Williams will be faced with No. 10 Sara Errani, who had not reached a semifinal at the U.S. Open before this year.
No. 3 Sharapova will take on top-seeded Victoria Azarenka, who despite her No. 1 world ranking, has only won one major championship -- this year's Australian Open -- and has not advanced past the fourth round at the U.S. Open in six previous appearances.
No. 2 Bob and Mike Bryan will also see action in the men's doubles final at noon as they take on No. 5 Leander Paes and Radek Stepanek.
