Federer pulls out of Shanghai Masters to rest

Roger Federer has pulled out of the Shanghai Masters next month to rest "nagging injuries" and ensure a six-week break.

Federer says on his website that he needs "necessary time to rest and recuperate after a long summer."

The 30-year-old Swiss played two Davis Cup singles matches and a doubles match in Australia last weekend, just days after losing in the U.S. Open semifinals in New York.

Federer's next scheduled match is Oct. 31 at his hometown Swiss Indoors event at Basel.

The third-ranked player apologized to his fans and says he looks forward to returning to Shanghai for the 2012 event.
