PARIS (REUTERS) - Maria Sharapova survived a string of unforced errors to book her place in the third round of the French Open on Friday with a 6-2, 6-4 rain-delayed win against Canada's Eugenie Bouchard.

The defending champion, seeded second at Roland Garros, returned to Court Philippe Chatrier leading 6-2, 4-2 after the match had been interrupted by rain late on Thursday.

Despite Bouchard's late fight and a total of 28 unforced errors from the Russian, Sharapova wrapped it up in 15 minutes on her first match point.

She will face China's Zheng Jie for a last-16 spot.
