Martina Navratilova

Martina Navratilova’s 59 Grand Slam titles across all disciplines is the most ever, outpacing #9 McEnroe by 52 majors. She held world No. 1 for 332 weeks, 1.95 times longer than the average all-time great. With 18 singles majors, her 9 Wimbledon singles titles tie Steffi Graf’s record, but Navratilova won 79% of those finals in straight sets versus Graf’s 67%. Her serve-and-volley dominance produced a 90.1% win rate on grass, a surface where she averaged 5.2 winners per game—1.4 more than any rival in the Open Era.
