World number one Novak Djokovic and defending champion Rafael Nadal reached the Monte Carlo Masters third round after straightforward victories on Wednesday in the season's first big claycourt tournament.
Nadal beat Finland's Jarkko Nieminen 6-4 6-3 while Djokovic defeated Italian Andreas Seppi 6-1 6-4.
Spaniard Nadal, who is chasing a record eighth consecutive victory in Monte Carlo, resumed full training last week after aknee injury forced him to pull out of his semifinals with Andy Murray in Miami. He showed no signs of the problem as he recorded his 40th win at the chic venue by the glittering Mediterranean, where he has been unbeaten since 2005.
The second seed will next play Kazakhstan qualifier Mikhail Kukushkin, who defeated Italian Filippo Volandri 7-6 2-6 6-2.
Djokovic, had a flying start to go 4-0 up but was less impressive afterwards and needed 88 minutes to edge out Seppi - ranked 44th in the world.
The top seed will take on 16th seed Alexandr Dolgopolov, who beat Australian teenager Bernard Tomic 6-2 5-7 6-1, in the third round.
