Maria Sharapova marked her rise back to the summit of the women's game by beating Sara Errani 6-3 6-2 to clinch her first French Open title and complete a career Grand Slam.

The 25-year-old, who on Monday will overtake Victoria Azarenka to become world number one for the first time in four years, is the 10th woman to win all four major tournaments, following in the footsteps of the likes of Martina Navratilova, Steffi Graf and Serena Williams.

Errani's brilliant run to the final, which included wins over Ana Ivanovic, Svetlana Kuznetsova and Sam Stosur, was one of the most surprising for many years but in the end Sharapova's extra power was simply too much.

For a brief moment Errani was the champion, but that was simply an error by the announcer that brought laughter all round, and it was not long before Sharapova was presented with the trophy by three-time winner Monica Seles.

Describing Seles as an inspiration, Sharapova said: "It's a magnificent moment in my career. I'm really speechless. It's been such a journey to get to this stage.

"I have so many people to thank, especially my wonderful team. But most importantly my mother and father. They're my rock, they keep me together and they've kept me going through all the tough times and the good times."

Errani will break into the top 10 on Monday, and she said: "I don't feel like top 10 but I will be top 10.

"It's incredible for me. I can't believe it and I'm so happy for that."
