NUSA DUA, Indonesia (AP) Aravane Rezai has won the Commonwealth Bank Tournament of Champions after top-seeded Marion Bartoli retired from the final with a thigh injury after losing the first set 7-5.

Bartoli was up 4-2 on Sunday 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.
