U.S. Open women's final postponed until Sunday

The U.S. Open women's final has been postponed until Sunday because of weather issues.

Victoria Azarenka and Serena Williams were slated to play for the championship on Saturday evening in New York, but rain delayed the start of the men's semifinals on Saturday afternoon. The first semifinal was completed, but the second was stopped in the first set.

Officials have slated the women's final for Sunday afternoon at 4 p.m. ET.

The top-seeded Azarenka will try for her second career Grand Slam title and second of 2012. The native of Belarus won the Australian Open back in January. She topped Maria Sharapova in Melbourne and also won the rematch on Friday in the U.S. Open semifinals, rallying for a 3-6, 6-2, 6-4 triumph.

Williams, seeded fourth for this year's fortnight, advanced Friday with a 6-1, 6-2 rout of Italy's Sara Errani. The American star needed a mere 63 minutes to reach her sixth U.S. Open final and on Sunday will try for her fourth title. She won the crown at Flushing Meadows in 1999, 2002 and 2008, falling in the 2009 final to Kim Clijsters and losing again last year to Samantha Stosur.

It's been a banner summer for Williams, who captured her 14th career Grand Slam title at Wimbledon in July and added Olympic gold to her outstanding resume at the London Games in August.

Williams beat Azarenka in the semifinals at both events and will carry a 9-1 record against the Belarussian into Sunday's match.
