It was the same for Federer, Williams and Sharapova. No matter how big a star you are, just getting that first-rounder out of the way, as well as the normal nerves that accompany it, makes for a good day.
Federer barely had to breathe heavily in his 6-1, 6-1, 6-3 rout of Italy's Paolo Lorenzi.
"I got the break, I think, in all three sets in the return game," the Swiss legend said. "I was always up in the score.… It's easier to play that way."
Williams was on Centre Court just long enough to get her racket strings stretched in her 6-1, 6-2 victory over fellow U.S. player Anna Tatishvili.
"I like the grass," Williams said. "There is so much history here. I like that. I like that everybody wears white."
Federer has won here seven times but was upset in the second round last year. This year, he has added former star Stefan Edberg to his support team, and that prompted questions about the possibility of more serving-and-volleying, which was Edberg's style.
"I think it could be that little extra piece to the puzzle that could bring me through … an extra option," Federer said.
Williams, who has won five Wimbledon titles, lost to Sabine Lisicki of Germany in the fourth round last year. She also lost early in the French.
"Whenever I slip," she said, "I try to get back up."
Sharapova, who won her Wimbledon title 10 years ago as a 17-year-old, also had a bad slip here last year, losing in the second round.
"This is a new day," she said. "It is not a new tournament, but it's a new opportunity."
