- Australian wildcard Bernard Tomic pulled out of the US Open on Thursday with a left hip injury, handing fourth-seeded David Ferrer a third-round berth.
Tomic, 21, said he'd also been battling flu prior to his first round victory over Dustin Brown, and when the hip pain flared he opted to take a conservative approach.
"I don't want to muck around with that area. It's painful," said Tomic, who retired after the first set of his first round match at the Australian Open against Rafael Nadal in January and underwent double hip surgery shortly thereafter.
"I can't afford to go on court and play against David and cause much more pain within myself," Tomic said. "I can potentially make it 10 times worse."
Tomic has endured a troubled year since January, coming back from surgery to suffer a record 26-minute defeat in his return to competition at Miami.
