Federer withdraws from Stockholm Open

Roger Federer has withdrawn from next week’s Stockholm Open, saying he needs to rest before starting his quest to reclaim the top spot in the world rankings.

Federer said in a statement on his Web site Wednesday that he had been playing catch-up all year after being diagnosed with mononucleosis at the start of 2008.

“I feel fortunate to be healthy again, but I want to remain at the top of the game for many more years to come and go after the No. 1 ranking again,” Federer said. “In order to do that, I need to get a proper rest and get strong again so that I am 100 percent fit for the remainder of the year or next year.”

Federer lost the No. 1 spot to Rafael Nadal, who beat him in both the French Open and Wimbledon final.
