The Graf–Navratilova rivalry was a tennis rivalry between Steffi Graf and Martina Navratilova, widely regarded as two of the greatest tennis players of all time. They met 18 times during their careers, and their head-to-head is even at 9–9,[1] with Graf having a 4–2 record in Grand Slam finals but Navratilova having a 5–4 record in overall Grand Slam matches (winning their last Grand Slam meeting despite being 34 at the time). They appeared in three consecutive Wimbledon singles finals (1987, 1988, 1989) and thrilled the fans with their enthralling tennis. Notably, despite how even their rivalry was, the age difference between Navratilova and Graf is more than 12.5 years.
