Hingis turned professional in 1994 and clinched her first WTA singles title in 1996 at Filderstadt. She went on to collect a total of 548 singles match wins, while her haul of 43 career singles titles is the 12th-most in WTA history. The Swiss star is also one of only six players to hold the WTA World No.1 ranking in singles and doubles at the same time.

Following two previous retirements, in 2003 and 2007, Hingis returned to professional tennis in 2013, and enjoyed phenomenal success in doubles, lifting 28 titles following her comeback. In a further testament to her extraordinary career, Hingis has announced her retirement while currently co-ranked World No.1 in doubles with Chinese Taipei’s Chan Yung-Jan, with whom she has won nine titles this year.

“Martina is a true champion and a great ambassador for the sport of women’s tennis,” said Steve Simon, WTA CEO and Chairman. “She has contributed greatly to the entire sport, both in her home country of Switzerland and across the globe. She will certainly be missed on our tour and with her accomplishments of holding the WTA No.1 ranking for 209 Weeks, 5 Grand Slam singles titles, 13 Grand Slam doubles titles and over 93 WTA singles and doubles titles she will be remembered as one of the greatest players to have played the game.”
