But perhaps more notable is her body of work on the tour. Over her three careers, she's racked up seven more singles titles than Maria Sharapova, and 23 more doubles titles than Sania Mirza.

Hingis and Venus Williams, both 37 years old, each appeared in the semifinals of their respective Singapore draws.

Hingis and Chan would fall in the semifinals to eventual champions Timea Babos and Andrea Hlavackova, while Williams lost in the singles final to Caroline Wozniacki.
