The No. 1 seeds will be in action on Sunday at the U.S. Open. Men's No. 1 Novak Djokovic will take on unseeded Joao Sousa as he tries to make it into a fourth round that already includes Rafael Nadal and Roger Federer, thanks to their Saturday matchups. No. 3 Andy Murray will be taking on Florian Mayer on the day, as well.
On the women's side, No. 1 Serena Williams will be taking on No. 15 Sloane Stephens. This has been one of the more anticipated matchups since the tournament draw was announced. Stephens beat Williams at the Australian Open in January and the two have had some drama in the media.
Williams had called herself a mentor to Stephens prior to their match, but Stephens suggested that Williams ignored her and shut her out after their matchup in Melbourne. The two have tried to move forward in the media, but that doesn't stop it from being a very anticipated matchup.
Other top seeds will be in action, like men's No. 5 Tomas Berdych and No. 12 Tommy Haas, as well as women's No. 3 Agnieszka Radwanska, who will take on No. 24 Ekaterina Makarova.
Sunday's TV schedule will be similar to Saturday's. CBS Sports Network will pick up coverage at 11 a.m. ET and run through 6 p.m. The Tennis Channel will pick up late coverage at 7 p.m. and will run through 11 p.m. You can find streaming video on U.S. Open Live, and if you want to listen in on the radio, there's U.S. Open.org Radio.
