Roger Federer won 20 Grand Slam singles titles, including a men's-record 8 Wimbledon crowns, and spent a men's-record 237 consecutive weeks at world No. 1. Renowned for his elegant all-court game, he was a cornerstone of the "Big Three" rivalry with Rafael Nadal and Novak Djokovic that defined men's tennis for close to two decades, retiring in September 2022 after the Laver Cup.
