ROGER FEDERER and Rafael Nadal both eased into the third round of the Monte Carlo Masters with straight-set victories.

Second seed Federer barely broke sweat as he saw off world No.35 Jeremy Chardy 6-2, 6-1 in under 55 minutes.

Eight-time winner Nadal also progressed with little fuss in Monaco, taking just 68 minutes to beat wild card Lucas Pouille 6-2, 6-1. His next opponent will be American John Isner, who beat Viktor Troicki 7-6 (7/4), 7-6 (7/5).

Defending champion Stan Wawrinka got the defence of his title off to a winning start by beating Argentina's Juan Monaco 6-1, 6-4.

The Swiss dropped just two points on his first serve, but will expect a bigger test in his third-round clash with Grigor Dimitrov.

The Bulgarian ninth seed broke Italian Fabio Fognini once in each set to secure a 6-4, 6-4 victory.

Roberto Bautista Agut, who turned 27 on Tuesday, emerged victorious from a gruelling three-setter against Philipp Kohlschreiber.

The German world No.25 edged the first set on a tie-break, but Bautista Agut bounced back to win 6-7 (3/7), 6-3, 7-6 (7/4) in two hours and 40 minutes.

Bautista Agut will next face sixth seed Tomas Berdych, who beat Sergiy Stakhovsky 6-4, 7-6 (7/2).

Tommy Robredo thrashed fellow-Spaniard Marcel Granollers 6-1, 6-1 while, in an all-French clash, 10th seed Gilles Simon was victorious against qualifier Benoit Paire 6-4, 7-5.

Simon was joined in the next round by compatriots Jo-Wilfried Tsonga and Gael Monfils, who overcame David Goffin and Alexandr Dolgopolov respectively.

Tsonga, the 11th seed, set up a clash against Marin Cilic with a 6-3, 6-4 success while Monfils prevailed 7-6 (7/5), 7-6 (8/6) and will next face Federer.

Fourth seed Milos Raonic came through 6-3, 7-6 (7/4) against Joao Sousa.
