Day 7 at the US Open focuses on the women as there are only 16 competitors left in the women's draw. A marquee match on Arthur Ashe highlights Sunday's action.
Sloane Stephens - Serena Williams: The marquee match of the tournament thus far pits the top player in the sport, Serena Williams, against perhaps the next great American player in Sloane Stephens. The Americans met earlier this year at the Australian Open. In a classic match, Williams won the first set, but was setback by an injury and Stephens was able to grab the win in a long three-set match. For Stephens, the win put her in her first grand slam semifinal. This is the first time the two have met since that match in January. Williams should have revenge on her mind and to remind the young American just who the best player in the world is.Stephens is playing some of the best tennis of her career and dominated fellow American Jamie Hampton in the third round. Expect another competitive match between these two players, but this time Williams will be the one who comes out on top.
Marcos Baghdatis - Stanislaw Wawrinka: A solid third round pairing pits veterans Baghdatis and Wawrinka. These two players have had their share of classic matches. Baghdatis lost a close five setter to Andre Agassi in 2006. While Wawrinka had world No. 1 Novak Djokovic on the ropes, before losing 12-10 in the 5th set at this year's Australian Open. Expect an entertaining match between these two players, but Wawrinka is in the better form and should advance to the Round of 16.
