Bartoli, Vinci reach Open GDF Suez quarters


PARIS (AP) -- Second-seeded Marion Bartoli of France beat Petra Martic of Croatia 7-5, 6-1 to reach the Open GDF Suez quarterfinals on Thursday.

Bartoli hit a forehand return winner to clinch the victory after winning seven consecutive games to lead 4-0 in the second set despite seven double faults.

Martic saved 16 break points but her form dropped in the final set.

Roberta Vinci of Italy, Klara Zakopalova of the Czech Republic and Germany's Mona Barthel and Angelique Kerber also advanced to the quarters.

Vinci beat American qualifier Bethanie Mattek-Sands 6-3, 1-6, 6-3. The seventh-seeded Italian broke twice in the final set, clinching victory when Mattek-Sands sent a backhand into the net.

Mattek-Sands struggled with her serve in the first set, making four double-faults and landing only 45 percent of her first serves. But she jumped out to a 5-0 lead in the next set to level the match when Vinci sent a forehand wide.

Mattek-Sands finished the match despite a lower back injury. She was in pain at 3-2 in the decider, sobbing during the changeover and calling a therapist to massage her left hip and thigh.

Barthel beat Pauline Parmentier 6-3, 6-0, hitting 26 winners to 6 for the French wild card. Barthel, who won the Hobart International last month in Australia, converted her second match point with a backhand crosscourt winner.

Zakopalova advanced to her first quarterfinal since the Korea Open in September, cruising past Tsvetana Pironkova 6-0, 6-3.

Kerber, a U.S. Open semifinalist, edged out Monica Niculescu of Romania 6-3, 4-6, 6-3.
