NEW YORK --Mardy Fish, the 23rd-seeded American who was scheduled to play top-seeded Roger Federer on Monday afternoon in a fourth-round singles match at the U.S. Open, abruptly withdrew from the tournament.
Fish, a 30-year-old who had missed part of this season after having treatment for an irregular heart beat, has a 1-8 career record against the 31-year-old Federer. Fish had played listless, error-filled tennis in his third-round match, a 6-1, 5-7, 7-6 (5), 6-3 win over 16th-seeded Gilles Simon, who had been hampered by a shoulder injury that kept many of his first serves less than 100 mph.
Fish's withdrawal means Federer is now into a Grand Slam quarterfinal for the 38thtime and is now tied with John McEnroe with the fifth-most match wins (65) at the U.S. Open in the open era of tennis. Jimmy Connors has the most wins with 98.
Last spring Fish was hospitalized because his heart rate had increased to three times its normal rate while he was resting. He had a procedure called cardiac catheter ablation May 23 that caused him to miss the French Open. Fish made it to the fourth round of Wimbledon but chose to skip the Olympics.
