John Isner and Tomas Berdych — the two highest-ranked players in the field — have withdrawn from the Winston-Salem Open, according to Bill Oakes, the tournament director.
Isner, the tournament’s two-time defending champion, is coming off a grueling tournament in Mason, Ohio. Isner — ranked No. 14 in the ATP rankings which came out Monday — had wins over three top-10 opponents at the Western & Southern Open, including a win over top-ranked Novak Djokovic in the quarterfinals. Isner lost to Rafael Nadal in Sunday’s final 7-6 (8), 7-6 (3).
Berdych, ranked No. 5, also had a strong run in the Western & Southern Open. He lost to Nadal 7-5, 7-6 (4) in Saturday’s semifinals.
The U.S. Open — the last of the season’s four major tournaments — is scheduled to begin Aug. 26.
