Graf's dominance might be considered one of her many contributions to tennis. She unseated some of the best players, and then consistently returned to top form throughout her professional career, scaring opponents with her forehand storke. "[It] puts fear in everybody," tennis professional Zina Garrison said of her forehand in Sports Illustrated. Tennis commentator Bud Collins even went so far as to dub her "Fraulein Forehand." When she retired following a series of injuries that made playing the game more burden than fun, Graf compiled an incredible record of 902 wins and 115 losses on the professional tour, with astonishing 107 career singles titles and 22 Grand Slam singles titles. She is one of only five players in the history of the game to win tennis' Grand Slam.
