In another early women's match Monday, former top-ranked Ana Ivanovic of Serbia advanced to the second round with a 7-6 (1), 6-0 win over qualifier Virginie Razzano of France.
The 12th-seeded Ivanovic, a semifinalist in 2007, swept through the second set in 22 minutes, finishing the match with her sixth ace. Another Serb, No. 16 Jelena Jankovic, beat Britain's Johanna Konta 6-2, 7-5.
The weather was cloudy but dry for the beginning of the two-week championships. Among those in the Royal Box were former U.S. Secretary of State Condoleeza Rice and Pippa Middleton, the younger sister of Prince William's wife, Kate.
Also scheduled on Centre Court was No. 2 seeded Andy Murray, playing Benjamin Becker of Germany.
Murray, who lost to Federer in last year's final, beat the Swiss star a month later for the Olympic gold medal and won his first Grand Slam at the U.S. Open. He is bidding again to become the first British player to win the men's Wimbledon trophy since Fred Perry in 1936.
Two-time champion Rafael Nadal, seeded No. 5 this year, was paired against Steve Darcis of Belgium on Court No. 1. Nadal is coming off his eighth victory at the French Open.
Defending women's champion and five-time winner Serena Williams plays Tuesday against Mandy Minella of Luxembourg.
