Some big names take the court at Arthur Ashe Stadium on Sunday, with Novak Djokovic playing in the men's semifinal and Serena Williams playing for the women's championship. Djokovic's match, with David Ferrer, is ongoing; Serena Williams will cap off the day's singles action at 3:30 PM CDT, playing against Victoria Azarenka for a shot at her 15th Grand Slam title. That'll be broadcast on CBS.
If that's not enough tennis for you, you'll be able to watch the women's doubles championship at 12:30—it's going down between Andrea Hlavackova and Lucie Hradecka and Sara Errani and Roberta Vinci. If that's not enough tennis for you, well, I don't have anything else to offer.
