Two semifinals in the women's draw highlight action from the U.S. Open on Friday as Serena Williams, Maria Sharapova, Sara Errani and Victoria Azarenka aim for berths in Saturday night's women's final.
The fourth-ranked Williams is looking her sixth U.S. Open final after winning the tournament in 1999, 2002 and 2008. No. 10 Errani and No. 1 Azarenka, though highly seeded, have both never reached a U.S. Open semifinal before 2012.
Sharapova will take on Azarenka in the first of the two semifinals after surviving a three-set battle with Marion Bartoli in the quarterfinals.
No. 2 Bob and Mike Bryan are also in action Friday. They take on No. 5 Leander Paes and Radek Stepanek in the men's doubles final, looking for their fourth U.S. Open title.
