Grand slam winners Li Na and Samantha Stosur made bright starts on the opening day at Wimbledon.

Li, who won the French Open last year, crushed Kazakhstan player Ksenia Pervak in the first match on Court 12.

The 30-year-old number 11 seed came through 6-3 6-1 in an hour and five minutes to repeat her first-round win over Pervak from January's Australian Open.

Stosur, seeded fifth and the reigning US Open champion, also had a straightforward route through to the second round as she opened proceedings on Court Three.

The 28-year-old Australian beat Spain's Carla Suarez Navarro 6-1 6-3 in an hour and two minutes.
