SOFIA (AP) - Ana Ivanovic overcame Sam Stosur 6-2, 5-7, 6-2 on Thursday for her second straight victory in the group stage at the season-ending WTA Tournament of Champions.
The two-time tournament winner played very aggressively to win the opening set in just 30 minutes. Stosur then broke Ivanovic s serve in the second set to go up 5-3. But Ivanovic got the early break at 2-0 in the third set and cruised from there. She will play Russia s Elena Vesnina on Friday with both players still trying to secure a spot in the semifinals.
Vesnina outlasted Bulgaria s Tsvetana Pironkova 6-2, 4-6, 6-0 for her first victory at the tournament.
In Thursday s last match, top-seeded Simona Halep of Romania swept past Ukraine s Elina Svitolina 6-1, 6-1, to finish the round-robin phase unbeaten.
She had already qualified for Saturday s semifinals.
