WIMBLEDON, England -- Second-seeded Rafael Nadal rallied for another five-set victory to reach the fourth round at Wimbledon, overcoming physical ailments and a warning for coaching.

The Spaniard battled back from two-sets-to-one down to defeat Germany's Philipp Petzschner 6-4, 4-6, 6-7 (5), 6-2, 6-3 in a 3½-hour Centre Court slugfest Saturday.

Earlier, Robin Soderling of Sweden advanced with a straight-sets victory over Thomaz Bellucci of Brazil. 

Nadal, who won the title in 2008 but missed last year's tournament due to knee troubles, called for the trainer several times for treatment on his left arm and right leg.

Petzschner, playing his third straight five-setter, also needed medical treatment on several changeovers.

Nadal was angry after receiving a warning from chair umpire Cedric Mourier in the fifth set for receiving coaching from coach and uncle Toni Nadal.

Nadal made the decisive break in the eighth game of the final set before holding serve to love to close out the match.

He will play unseeded Frenchman Paul-Henri Mathieu for a berth in the quarterfinals.

Sixth-seeded Soderling, a two-time French Open finalist, beat the 24th-ranked Bellucci 6-4, 6-2, 7-5 in a little less than two hours.

After breezing through the first two sets, the Swede faced a stiffer challenge from the left-handed Brazilian in the third, when he saved three break points in the penultimate game of the match.

Soderling is one of only three men yet to drop a set at Wimbledon, where he has reached the round of 16 for the second consecutive year.

He will play the ninth-seeded David Ferrer.
