Serena Williams will have to wait before continuing her bid for a calendar-year Grand Slam: Her U.S. Open semifinal was postponed because of rain in the forecast.

The top-seeded Williams was supposed to face 43rd-ranked Roberta Vinci on Thursday night at Flushing Meadows, N.Y., but the U.S. Tennis Association — citing a prediction of "rain throughout the evening" — pushed both women's semifinals to Friday. The first women's match, a semifinal between No. 2 Simona Halep and No. 26 Flavia Pennetta, will begin at 10 a.m. Central time, followed by Williams-Vinci. The men's semifinals will begin in late afternoon.
