Roger Federer is, of course, at the All England Club looking for his ninth Wimbledon title—but before the man considered by many to be the greatest tennis player in history hit the grass courts, he hung out with Vogue to answer 73 questions. Just two days before this year’s tournament began, Federer took a break from the practice courts to show us around and tell us what it’s like to be a legend of the game. Not only did he bring Vogue onto Centre Court—he answered our wonkiest tennis questions: What’s his signature shot? The victories he savors most? Why doesn’t he have a two-handed backhand? The 20-time Grand Slam tourney winner also clues us in on his other famous friends in the sport, the best style tips he has been given, his favorite Wimbledon traditions—and drops in to deliver some sage advice to a few lucky Wimbledon ball boys and ball girls (after stealing some of their strawberries and cream).
