Billie Jean King
King gained a record of 39 Grand Slam trophies throughout her tennis career, including 12 singles, 16 women’s doubles, and 11 mixed doubles. She’s used her No. 1 status to advocate for women’s rights since then.
Maria Sharapova
In women’s tennis, Sharapova seems to have a remarkable run. Even after several career-ending injury issues, Sharapova holds records that are second only to Williams, Graf, Navratilova, and Chris Evert in her sport.
