(CNN) -- Maria Sharapova completed her French Open preparations with a straight sets win over Germany's Kristina Barrois to win the WTA tournament in Strasbourg on Saturday.
The Russian top seed was a late entry to the clay court tournament but ended the week with her second title of the year.
Sharapova has only recently returned to the circuit after an injury layoff, but gained valuable match practice for the second grand slam of the season which starts in Paris on Sunday.

It was the 22nd title of her career and second on clay since Amelia Island in 2008.
Meanwhile, up and coming Romanian Alexandra Dulgheru beat Chinese fifth seed Zheng Jie 6-3 6-4 to retain the title at the WTA event in Warsaw.
Dulgheru raced into a 5-2 lead in the first set before Zheng broke back to only to lose her own service and the opener.
Zheng took a 4-2 lead in the second set but Dulgheru then strung together a run of four straight games to keep her grip on the trophy for the second year.
"Fatigue was starting to affect me and my opponent was very strong," world number 32 Dulgheru told the official WTA Tour Web site.
Dulgheru had put out Zheng's compatriot and third seed Li Na in the semifinals and will travel to Roland Garros as a dangerous outsider in the draw.
