Rafael Nadal has survived losing the opening set to Martin Klizan to advance into the third round of the French Open.

Klizan found his serve straight away and took advantage of some early Nadal errors to force a break in the seventh game, which was enough to hand him the opening set.

Nadal was in no mood for a repeat and raced into a 4-0 lead in the second before being broken. However, the form early in the set was enough to give the Spaniard a 6-3 second-set win.

In the third it still wasn't plain sailing for the master of clay and there were still errors in his game, but this time Klizan could not capitalise and the Spaniard was just good enough to claim the third too.

In the fourth Nadal broke early, but could not capitalise on his advantage and Klizan battled straight back.

After that Nadal found his groove and moved 5-1 ahead, but Klizan had not read the script and broke once more with Nadal serving for the match.

Nadal had a match point on the Slovakian's next serve, but it was saved to force the Spaniard to try to serve again for the match. This time he made no mistake and took the match 4-6 6-3 6-3 6-3 to move on to face Fabio Fognini.
