Rafa Nadal and Roger Federer are both safely through to the second round at Wimbledon.

Nadal had to recover from losing the opening set of his match against Slovakia's Martin Klizan on centre court.

But the men's second seed responded to win the next three sets 6-3 to secure victory.

Earlier, Federer made an impressive start to his campaign with a straight sets win over Italy's Paolo Lorenzi.

On court at the moment, Serena Williams is already leading by a set to love against fellow American Anna Tatishvili.

There were also wins today for the likes of Maria Sharapova, Jo-Wilfried Tsonga, Lleyton Hewitt, Stanislas Wawrinka and Caroline Wozniacki.

But women's 14th seed Sara Errani is out after a defeat to Caroline Garcia of France.
