Roger Federer is retiring from professional tennis at age 41 after a series of knee operations, closing a career in which he won 20 Grand Slam titles, finished five seasons ranked No. 1 and helped create a golden era of men's tennis with rivals Rafael Nadal and Novak Djokovic.
Novak Djokovic continues his historic run chasing the calendar-year Grand Slam with his win today at Wimbledon. If completed he will be the first player since Steffi Graff, who accomplished the feat in 1988. Djokovic won 6-7 (4), 6-4, 6-4, 6-3 over Matteo Berrettini.
