Paris - Australian Samantha Stosur wasted little time in a 6-4 6-0 first-round dismissal of Britain's Elena Baltacha as the French Open got underway in bright sun and clear skies on Sunday.

The sixth-seeded Stosur, a Roland Garros runner-up in 2010, needed just over an hour to see off the world number 68 in front of a sparce crowd on Court Philippe Chatrier.

Stosur ran into a spot of bother when Baltacha broke back in the ninth game but she upped the pace and won the remaining seven games, ending her opponent's ordeal with a return winner.

Later on Sunday, local favourite Jo-Wilfried Tsonga, the fifth seed, will entertain Russian Andrey Kuznetsov and American Venus Williams will start her campaign against Argentine Paula Ormaechea.– Reuters
