She was ranked as the world No. 1 in women's singles by the Women's Tennis Association (WTA) for 209 weeks (fifth-most of all time) and as the world No. 1 in women's doubles for 90 weeks, holding both No. 1 rankings simultaneously for 29 weeks. Hingis won 43 WTA Tour-level singles titles and 64 doubles titles, including a total of 25 major titles: five in singles, 13 in women's doubles (including the Grand Slam in 1998), and seven in mixed doubles.
