Martina Hingis

Martina Hingis (German pronunciation: [maʁˈtiːna ˈhɪŋɡɪs], Slovak: Martina Hingisová; born 30 September 1980) is a Swiss former professional tennis player. Hingis was the first Swiss player, male or female, to win a major title and to attain a world No. 1 ranking. She spent a total of 209 weeks as the singles world No. 1 and 90 weeks as doubles world No. 1, holding both No. 1 rankings simultaneously for 29 weeks. She won five major singles titles, 13 major women's doubles titles (including the Grand Slam in 1998), and seven major mixed doubles titles, for a combined total of 25 major titles. In addition, she won the season-ending WTA Finals two times in singles and three in doubles, an Olympic silver medal in doubles, and a record 17 Tier I singles titles.

Hingis set a series of "youngest-ever" records during the 1990s, including youngest-ever Grand Slam champion and youngest-ever world No. 1. Before ligament injuries in both ankles forced her to withdraw temporarily from professional tennis in early 2003, at the age of 22, she had won 40 singles titles and 36 doubles titles and, according to Forbes, was the highest-paid female athlete in the world for five consecutive years, 1997 to 2001. After several surgeries and long recoveries, Hingis returned to the WTA Tour in 2006, climbing to world No. 6, winning two Tier I tournaments, and receiving the Laureus World Sports Award for Comeback of the Year. She retired in November 2007 after being hampered by a hip injury for several months. In January 2008, the International Tennis Federation suspended Hingis for two years following a positive test for a metabolite of cocaine in 2007.

In July 2013, Hingis again returned from retirement to play the doubles events of the North American hardcourt season. During her doubles-only comeback, she won four major women's doubles tournaments, six major mixed doubles tournaments (completing the career Grand Slam in mixed doubles), 27 WTA Tour titles, and the silver medal in women's doubles at the 2016 Rio Olympics. Hingis retired for the third and final time after the 2017 WTA Finals, while ranked as the world No. 1.

Widely considered an all-time tennis great, Hingis was ranked by Tennis magazine in 2005 as the eighth-greatest female player of the preceding 40 years. She was named one of the "30 Legends of Women's Tennis: Past, Present and Future" by TIME in June 2011. In 2013, Hingis was elected into the International Tennis Hall of Fame, and was appointed two years later the organization's first ever Global Ambassador.
