Federer, 31, a five-time U.S. Open champion from Switzerland, now has reached at least the quarterfinals in 34 straight Grand Slam tennis tournaments.
Fish, seeded 23rd and one of only two American men left in the tournament, had reached the fourth round with a five-set win against France’s Gilles Simon that lasted until 1:10 yesterday morning. Organizers announced Fish’s withdrawal in an e-mailed statement.
Federer will meet 26-year-old Tomas Berdych, the sixth seed from the Czech Republic, who won 7-6 (7-4), 6-4, 6-1 today against No. 11 Nicolas Almagro of Spain. Berdych had 17 aces as he reached the quarterfinals of the U.S. Open for the first time in 10 tries.
Ana Ivanovic advanced to the quarterfinals for the first time in her career with a 6-0, 6-4 win today against Tsvetana Pironkova of Bulgaria.
Ivanovic, 24, the women’s 12th seed from Serbia, won the French Open in 2008 and has reached at least the semifinals at Wimbledon and the Australian Open. Until today, she had never made it past the fourth round at the U.S. Open.
Ivanovic’s victory ended about 10 hours after American John Isner lost a match that tied the latest finish in tournament history.
Isner, who at No. 9 was the top American in the men’s draw, was knocked out with a five-set loss to 19th-seeded Philipp Kohlschreiber of Germany that ended at 2:26 a.m. today. It matched the record for the latest finish in U.S. Open history, a 1993 second-round meeting between Swedes Mats Wilander and Mikael Pernfors.
“It was really late, so everyone who was here is really a crazy tennis fan,” Kohlschreiber said in a televised interview after his 6-4, 3-6, 4-6, 6-3, 6-4 win. “It was great for me and I thought we played some really good tennis.”
Isner’s loss and Fish’s withdrawal left Andy Roddick as the only American left in the men’s singles draw at the National Tennis Center in New York. Roddick, 30, has said he will retire at the end of the tournament.
Serena Williams, a three-time women’s singles champion at the U.S. Open, is scheduled to play twice today in Arthur Ashe Stadium. The women’s fourth seed will meet Andrea Hlavackova of the Czech Republic for a spot in the quarterfinals in the afternoon and then return for a doubles match with older sister Venus Williams during the night session.
Also in the women’s draw today, No. 2 Agnieszka Radwanska of Poland meets No. 20 Roberta Vinci of Italy. Third-seeded Andy Murray of Britain meets No. 15 Milos Raonic of Canada tonight for a spot in the men’s quarterfinals.
