Martina Hingis is a former world number one Swiss tennis player. Known as the “Swiss Miss,” she has won five Grand Slam singles titles (three Australian Open, one Wimbledon, and one US Open). She has also won nine Grand Slam women’s doubles titles, winning a calendar year Grand Slam in 1998, and one Grand Slam mixed doubles title. She set a series of “youngest-ever” records before ligament injuries in both of her ankles forced her to withdraw from professional tennis at the relatively early age of 22.
On November 29, 2005, after several surgeries and long recuperations, Hingis returned to the WTA tour at a tournament in Gold Coast, Australia in January 2006. Since then, Hingis has climbed to No. 6 in the world rankings, won three titles (at the Tier I tournament in Rome, the Tier III tournament in Kolkata, India, and the Tier I tournament in Tokyo), was the runner-up in two tournaments (Tier I tournaments in Tokyo and Montreal), and qualified for the 2006 WTA Tour Championships in Madrid.
