To get you started for Sunday, here is what to watch during Day 7 at the U.S. Open. (Reminder: Listed start times are not precise.)
|U.S. Open Day 7|
Djokovic is looking for a spot in the fourth round and has reached at least the quarterfinals in 13 consecutive Grand Slam tournaments dating back to 2009.
Over on the Armstrong court, wild card Lleyton Hewitt takes on No. 4 seed David Ferrer. This could be an interesting match for Hewitt. He lost the first set in both the first and second round matches before rallying to victory. Ferrer has had an awesome Grand Slam season, reaching the quarterfinals in the Australian Open and Wimbledon, while making the semifinals at the French Open.
1:30 p.m.: Could this be it for Andy Roddick? He annouonced his retirement after the U.S. Open so this could be the final match of his career. He'll take on Fabio Fognini, who dominated Guillermo Garcia-Lopez in the second round on the way to a 6-4, 6-4, 6-2 victory.
4 p.m.: We turn our focus to two women's matches as No. 1 seed Victoria Azarenka takes on Anna Tatishvili on Arthur Ashe stadium. Over on Armstrong Stadium, women's defending champion Samantha Stosur takes on Laura Robson. If both Azarenka and Stosur advance (and they should) this would set up a huge quarterfinal match between the two women.
(The night session can be found on the Tennis Channel)
7 p.m.: No. 3 seed Maria Sharapova plays the first match of the night session, taking on No. 19 seed Nadia Petrova. Sharapova has only reached the quarterfinals once at Flushing Meadows, while Petrova hasn't reached the quarterfinals at the U.S. Open since 2005. Should be a great one.
9 p.m.: The final match of the night features the highest-ranked American No. 9 John Isner taking on No. 19 seed Philipp Kohlschreiber. If this is one of those five set marathons, don't worry Monday is a holiday.
