The title was Hingis's first since winning the doubles in
Doha in 2007.
Since retiring that year, Hingis, a former-world number one, has
flirted with a doubles comebacks.
Last year the winner of five singles and nine doubles grand slam
career titles attempted a return with Daniela Hantuchova but
found little success, winning just three-of-five matches and
falling in the first round of the U.S. Open.
Hingis launched a second comeback this season, losing in the
first round of Indian Wells, but looked right at home on the
Miami hardcourts, returning to the winner's circle at an event
she won twice (1998-99).
