Maria Sharapova became only the tenth woman to win all four Grand Slam titles as she stormed to victory at the French Open, beating Italian Sara Errani 6-3, 6-2, on Saturday.

Sharapova, the second seed at Roland Garros, first shot to fame in 2004 when she came out of nowhere to win the women's title at Wimbledon, completed a memorable week, as she also moved to the top of the WTA rankings for the first time in four years.

The straight sets victory came over the Italian, playing in her first Grand Slam final, on Sharapova's third match point, as she looked comfortable throughout.

The Russian broke Errani, the 21st seed, five times in the course of the two sets, her experience and superior strength of her 6'2" frame proving to be too much for Errani, who earned two breaks of her own.

While she will be disappointed to lose in the final, her first in a Grand Slam, Errani can take some solace in her doubles victory alongside compatriot Roberta Vinci, with whom she defeated Maria Kirilenko and Nadia Petrova.

Sharapova, meanwhile, joins Serena Williams, Steffi Graf, Martina Navratilova and Billie Jean King among others as one of only ten women to win the Australian Open, Roland Garros, Wimbledon and US Open in their career.

It also fully marks Sharapova's return to the top of the game, having slipped into the second tier of the women's game through a string of injuries and near-misses, having lost her past three Grand Slam finals.
