Eight-time defending champion Rafael Nadal extended his Monte Carlo Masters winning streak to 44 matches by beating Philipp Kohlschreiber 6-2, 6-4 Thursday, while second-ranked Andy Murray was routed 6-1, 6-2 by Stanislas Wawrinka in the third round.
Murray dropped serve five times and made a number of unforced errors, lasting less than an hour against the 13th-seeded Wawrinka, who had won their two only previous meetings on clay. Murray was jeered off the court.
"Just looked at the stats ... 24 unforced errors is far too many. That's a set's worth. That's where half the points went," a despondent Murray said. "I hope that's not going to be the case over the next five, six weeks. I've had tough losses on the clay before and I've come back well from them. Hopefully today will be the same."
Earlier, Nadal dispatched Kohlschreiber without facing a single break point. The Spaniard will face Bulgaria's Grigor Dimitrov.
"He's playing well," Nadal said. "He's able to play very well, very aggressive, very good technique. He's (a) complete player."
Jo-Wilfried Tsonga also advanced with a 6-3, 6-0 win against Jurgen Melzer, breaking the Austrian player four times. Tomas Berdych again struggled on his serve as he lost 6-4, 6-2 to Italian Fabio Fognini.
"It's difficult to assess my game because he was not really playing his best," Tsonga said. "But I'm happy I was able to do the job. When you play tennis, you always try for perfection."
Fognini will play seventh-seeded Richard Gasquet, who defeated Marin Cilic 7-5, 6-4.
Later, top-ranked Novak Djokovic will face Juan Monaco.
Nadal clipped a forehand winner past Kohlschreiber to break and held at love to move up 5-3 in the second set. The Spaniard served out the match, clinching victory when the German scooped a backhand into the net.
