Martina Navratilova

Martina Navratilova revolutionized women's tennis with her aggressive serve-and-volley style, supreme athleticism, and a pioneering dedication to fitness and training. She won 18 Grand Slam singles titles, including a record nine Wimbledon championships. Her rivalry with Chris Evert is one of the most iconic in sports. Navratilova's longevity is staggering; she won majors across four decades and remained a top competitor into her late 30s. Her dominance extended to doubles, where she is arguably the greatest ever, winning 31 major women's doubles titles and 10 mixed doubles titles for a combined 59 Grand Slam trophies. She held the World No. 1 ranking for 332 weeks and set a modern record with a 74-match winning streak in 1984.
