Aravane Rezai won the Commonwealth Bank Tournament of Champions when top-seeded Marion Bartoli retired with a thigh injury Sunday after losing the first set 7-5 in the final.
Bartoli was up 4-2 and then had a set point in the ninth game before the 44th-ranked Rezai broke back to level at 5-5.
Bartoli then needed medical treatment on her left thigh in the 12th game. She continued to play but double-faulted to hand Rezai the set and then retired.
It was Rezai's second title of the year after winning in Strasbourg.
