Former Australian Captain March 22, 2008
WORLD No.1 Roger Federer reached the last four of the Pacific Life Open in Indian Wells without hitting a shot when his quarter-final opponent German Tommy Haas pulled out with a sinus infection.
Federer, three times champion at Indian Wells and seeking his first ATP title of the year, will next meet No.7 seed David Nalbandian of Argentina or American Mardy Fish, who were playing later today.
“I deeply regret that I have to withdraw,” Haas said in a statement. “I was playing my best tennis of the season and was looking forward to playing Roger this afternoon.
“I am sure the tennis will be incredible this weekend and I look forward to returning again next year.”
The 29-year-old, a former world No.2 whose career has been dogged by a series of injuries, produced an impressive run this week, knocking out No.6 seed Andy Roddick and No.11 seed Andy Murray.
Top seed Federer, who has beaten Haas eight times in 10 career meetings, said: “I am very sorry for Tommy as I was looking forward to another great match with him.
“We have played quite a few times and I know and respect Tommy a lot. I hope he gets better quickly.”
Sunday’s remaining semi-final will be between holder Rafael Nadal of Spain, who is seeded second, and No.3 seed and Australian Open champion Novak Djokovic of Serbia.
