Sania Mirza (Hindustani pronunciation: ; born 15 November 1986) is an Indian professional tennis player. A former world No. 1 in the doubles discipline, she has won six Grand Slam titles in her career. From 2003 until her retirement from singles in 2013, she was ranked by the WTA as India's No. 1 player in both the categories. Throughout her career, Mirza has established herself as by far the most successful Indian women's tennis player ever and one of the highest-paid and most high-profile athletes in the country.
In her singles career, Mirza had notable wins over Svetlana Kuznetsova, Vera Zvonareva, and Marion Bartoli, as well as former world No. 1s Martina Hingis, Dinara Safina, and Victoria Azarenka. She is the highest-ranked female player ever from India, peaking at world No. 27 in mid-2007. However, a major wrist injury forced her to give up her singles career and focus on the doubles circuit. She has achieved a number of firsts for women's tennis in her native country, including surpassing $1 million in career earnings (in the end over $6.9 million), winning a singles WTA title, and winning six major titles (three each in women's doubles and in mixed doubles), as well as qualifying for (and eventually winning) the WTA Finals in 2014 alongside Cara Black, defending the title the following year partnering with Martina Hingis.
