MONACO — 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.
Novak Djokovic put his sore right ankle to the test again, rallying from a set down to beat Juan Monaco of Argentina 4-6, 6-2, 6-2.
Djokovic will play Jarkko Nieminen in the quarterfinals after the Finn edged Juan Martin del Potro of Argentina 6-4, 4-6, 7-6 (4).
Nieminen sealed victory on his second match point when del Potro sent a big forehand wide.
Murray also dropped serve five times and made a number of unforced errors. He lasted less than an hour against the 13th-seeded Wawrinka, who had won their two only previous meetings on clay.
