Roger Federer

London: Roger Federer walked into the Wimbledon quarter finals when his fourth-round opponent, Tommy Haas, withdrew from the tournament on Sunday with a torn stomach muscle.

The 13th-seeded Haas and four-time defending champion Federer were scheduled to play in the fourth round on Monday.

“To pull out of this match, against Roger on Centre Court, is obviously very disappointing,” Haas said. “Can’t even put it in words.”

The top-ranked Federer will face 2003 French Open champion Juan Carlos Ferrero or unseeded Serb Janko Tipsarevic for a berth in the semis.

Because Haas pulled out before the match, it goes into the books as a walkover, and Federer will not get credit for a victory. So the Swiss star’s winning streak at Wimbledon stays at 31 matches, and his record run on grasscourts stays at 51.

Haas said he expects to be sidelined for up to a month with the lower abdominal injury, which flared up during his 1-6, 6-4, 7-6 (7-5), 6-4 victory over No. 21 Dmitry Tursunov in the third round on Friday.

Haas called for the trainer during the second set, when he was treated and given painkillers. The German said the pain felt much worse on Saturday and that tests showed the muscle was bleeding.

The match against Federer was to be the 29-year-old Haas’s first in the fourth round at the All England Club.

“Who knows if such an opportunity will come again,” Haas said. “I certainly hope so.”
