Five-time Grand Slam singles champion Martina Hingis, 32, was elected to the International Tennis Hall of Fame on Monday. Hingis won 15 major titles, including nine in women's doubles and one in mixed. The first came at Wimbledon in women's doubles in 1996, at the age of 15 years, 9 months, making her the youngest Grand Slam event champion in history.
Also elected on Monday were Cliff Drysdale, Charlie Pasarell and Ion Tiriac.
Hingis, who retired in 2007, spent a total of 209 weeks ranked No. 1 in her career. She won 43 singles titles in her career.
The only blemish was the cause of her retirement: She was given a two-year suspension for a positive cocaine test, and retired rather than serve the suspension. She denied using cocaine, but never appealed the ruling.
Drysdale played in the 1960s and 1970s and reached a career-high ranking of No. 4, then helped start the ATP men's tour, serving as its first president from 1972 to 1974.
Pasarell was an NCAA champion at UCLA in 1966 and a member of the U.S. Davis Cup team. Like Drysdale, he was a key figure at the start of the ATP and helped grow the sport.
Tiriac has held key roles as a coach, player manager and tournament promoter. His most noted client was Hall of Fame member Boris Becker.
Michael Stich and Helena Sukova were nominated for induction but fell short of election.
