| Younger sister of Venus Williams, also a grand slam champion, Serena won her first grand slam aged 17 and by 22 had completed a career Grand Slam in singles and doubles. She recovered from a career threatening injury to win Olympic Gold in 2012, becoming the only player (male or female) to win every major singles and doubles title. Her Australian Open triumph in 2017 meant she finally overtook Steffi Graf for most Grand Slam singles titles (23). Aged 36 Serena is still the dominant force in the women's game. |
