Defending champion Maria Sharapova led 19-year-old Eugenie Bouchard of Canada 6-2, 4-2 before rain interrupted their second-round match at the French Open on Thursday.

The 26-year-old Sharapova, who completed a career Grand Slam by winning at Roland Garros last year, secured a break in the fifth game of the second set and held as she closed in on victory.

But play was interrupted late in the next game as rain came down again. Both players sat under umbrellas for a few minutes before walking off. Play was then suspended for the day.

Bouchard, last year's Wimbledon junior champion, traded big shots with Sharapova at the start of the second set, troubling her with some heavy forehands.

Bouchard lost to Alize Cornet in the semifinals of the Strasbourg International last week.
