Roddick, the 2003 U.S. Open champion, and Sports Illustrated swimsuit model Brooklyn Decker became husband and wife at his Austin, Texas, home, a guest at the wedding told The Associated Press on Saturday.
Elton John sang for the bride and groom at a reception held at a country club after the ceremony Friday night, the guest said, speaking on condition of anonymity because it was a private function not open to the media.
People.com first reported about the wedding.
The 26-year-old Roddick announced his engagement to the 22-year-old model in March 2008.
Roddick finished 2003 ranked No. 1. He is currently No. 6.
Federer, who owns 13 Grand Slam singles titles, married longtime girlfriend Mirka Vavrinec last weekend in a small ceremony in his hometown of Basel, Switzerland.
