After the skies opened yesterday and Mother Nature visited the rain-soaked courts of the USTA Billie Jean King National Tennis Center, Day 10 of the 2011 U.S. Open features a schedule packed with two men's singles quarterfinals matches, four men's singles matches to determine quarterfinalists, and four women's singles matches that will narrow the field down to four semifinalists. Today could be a banner day at the 2011 U.S. Open for American players, as four are still in contention, including women's quarterfinalist Serena Williams, and three on the men's side seeking a trip to the quarterfinals, the unseeded Donald Young, the 28th-seeded John Isner and the number 21-seed, Andy Roddick.

Today too, the skies are overcast in Flushing Meadows, N.Y. with a 60 percent chance of rain, so today's schedule remains in jeopardy, but if things go off as planned, the number two seeded Rafael Nadal from Spain will face the unseeded Gilles Muller of Luxembourg at 11:00 a.m. at Arthur Ashe Stadium to determine who will advance to the quarterfinals. Following this match, also at Ashe Stadium, a matinee quarterfinals match between the top-seeded Novak Djokovic from Serbia and his fellow countryman, the number 20 seed, Janko Tipsarevic, will take place.

Meanwhile at Louis Armstrong Stadium at 11:00 a.m., fourth round action on the men's side will feature the number five seed, Spaniard David Ferrer facing the 21st-seeded American Roddick, followed by a women's quarterfinals match between the number eight seed, Australian Samantha Stosur and the second-seeded Vera Zvonareva from Russia.

On the Grandstand at 11:00 a.m., the number four seeded Andy Murray from Great Britain faces the unseeded American Young for a shot at the quarterfinals, followed by another quarterfinals qualifier as the 28th-seeded American Isner faces the 12-seed, Gilles Simon from France. Following the men's matches on the Grandstand, the women's field narrows even further with the quarterfinals match between unseeded German Angelique Kerber and the number 26 seed, Italy's Flavia Pennetta.

Another women's quarterfinals match of note takes place in the afternoon at Louis Armstrong, as top-seeded Caroline Wozniacki from Denmark faces the upstart 10th-seeded German, Andrea Petkovic.

Under the lights at Arthur Ashe Stadium, a pair of matches take place if the rain holds off. Getting things started at 7:00 p.m. will be the 28th-seeded American Serena facing the number 17-seed, Russian Anastasia Pavlyuchenkova. Rounding out Day 10 action will be the second men's quarterfinals match of the day, featuring the three seed, Switzerland's Roger Federer taking on the 11-seed, France's Jo-Wilfried Tsonga, to see who will advance to the final four on the men's side.

In women's doubles action, the team of American Vania King and her partner, Kazakhstan's Yaroslava Shvedova, the number three seeds, will face the number eight-seeded women's doubles team of Andrea Hlavackova & Lucie Hradecka from the Czech Republic on Court 17 at 11:00 a.m. Another women's doubles quarterfinals match features the number four seeds, the American duo of Liezel Huber & Lisa Raymond, as they face the ninth-seeded duo from the Czech Republic, Iveta Benesova & Barbora Zahlavova Strycova also on Court 17.
