On a day filled with far more rain drops than drop shots at Wimbledon, light but persistent, showers prevented the completion, or even start, of dozens of matches. Roger Federer and Andy Murray provided the highlights. 

The retired Federer, who won a men’s-record eight of his 20 Grand Slam titles at the All England Club, was in the front row of the Royal Box, where he sat next to Kate, the Princess of Wales. Federer was saluted with a 1 1/2-minute standing ovation during a pre-match tribute to his career at Centre Court on Tuesday.
