Kim Clijsters and Petra Kvitova The day before the rankings showed Kim Clijsters has ascended the ladder to World No. 1 once again, she was upset by Petra Kvitova in the final of the Open Gaz de France, 6-4, 6-3.

”I would like to dedicate this trophy to my grandfather, who passed away last week,” Kvitova said. ”I played for my grandfather. I’m happy I won the tournament for him.”

Kvitova has now won 16 of 17 matches this season, and earned the WTA Newcomer of the Year award last season. Kvitova is ranked No. 14 in the new rankings that came out today.

Clijsters slammed an ace to save a match point but Kvitova converted her second match point with a forehand winner.

”I think in the past matches where I beat her, she showed some of the best tennis but it wasn’t quite consistent,” said Clijsters, who won their two previous meetings. ”Today she was very consistent in her level, so she deserved to win because she was better.”
