The 33-year-old Hingis, former world No. 1 who quit tennis after testing positive for cocaine, and Germany's Sabine Lisicki defeated the Russian team of Ekaterina Makarova and Elena Vesnina 4-6, 6-4, 10-5 in Sunday's doubles final at the Crandon Park Tennis Center.
Hingis, a five-time Grand Slam champion, retired after testing positive for cocaine at Wimbledon in 2007 and receiving a two-year suspension.
She resumed playing doubles last summer, coaching and teaming up with Lisicki on the tour.
The Sony Open is one of the biggest hard-court events on the ATP and WTA calendars.
