Tennis great Rafael Nadal announced his impending retirement from the sport on Thursday at age 38 after winning 22 Grand Slam singles titles during an unprecedented era he shared with his rivals in the so-called Big Three, Roger Federer and Novak Djokovic.

In the years that followed, Nadal worked to improve his all-court game and his serve, and his results away from clay improved. He missed the Australian Open in 2006 but won his second Roland Garros title before reaching that year’s Wimbledon final and U.S. Open quarters. Roger Federer schooled him on Centre Court, winning the first set 6-0.

Fittingly, his bookend Grand Slam titles came at Roland Garros, and it’s impossible to discuss Nadal's career without mentioning that site. Still, it’s also important to remember that he completed a career Grand Slam, earning at least two trophies at each of his sport’s four most prestigious tournaments.
