Djokovic starts defence with win
Novak Djokovic made a convincing start to the defence of his Monte-Carlo Rolex Masters title with a second-round thrashing of Albert Montanes.
The world number two, who received a first-round bye, ended Rafael Nadal's eight-year winning streak by the Mediterranean last year and needed just 45 minutes to dispatch Montanes 6-1 6-0.
The first set was more competitive than the scoreline suggested but Spaniard Montanes won only five points in the second as Djokovic strolled through.
The Serbian, who lives in Monte Carlo, told Sky Sports: "It was my first match on this surface since Roland Garros so you never know how you're going to react and today I lost only one game so there are not too many bad things I can say about my game."
Also into the third round is ninth seed Jo-Wilfried Tsonga, but the Frenchman had a much tougher time in beating Germany's Philipp Kohlschreiber 6-4 1-6 6-4.
Twelfth seed Grigor Dimitrov needed three sets to beat Marcel Granollers 6-2 4-6 6-2 in the first round but there were defeats for Mikhail Youzhny and Jerzy Janowicz.
Thirteenth seed Youzhny was beaten 6-3 7-6 (7/4) by Italian Andreas Seppi while Janowicz's miserable run continued with a 6-4 6-2 loss to Michael Llodra.
The Pole, who has struggled since reaching the Wimbledon semi-finals last summer, has lost his last six matches.
Fifth seed Tomas Berdych beat Dmitry Tursunov in two tight sets, 7-5 6-4, to reach the third round while David Ferrer progressed to the same stage as the sixth seed brushed aside France's Jeremy Chardy 6-3 6-0.
There was success for Ferrer's fellow Spaniards in round one as 15th seed Nicolas Almagro ousted Paul-Henri Mathieu 6-3 6-2, lucky loser Pablo Carreno Busta upset Croatian Ivan Dodig 6-3 6-3 and Guillermo Garcia-Lopez won 6-3 6-2 against Benjamin Balleret.
Despite Chardy and Mathieu's exits, there was some cheer for the French fans in nearby Monaco as Gael Monfils eliminated 14th seed Kevin Anderson 6-4 7-6 (6/4) and Julien Benneteau beat Jurgen Melzer 6-4 3-6 6-4. Gilles Simon, though, lost 4-6 6-4 6-4 to Russian qualifier Teymuraz Gabashvili.
There were also wins for Marin Cilic and Yen-Hsun Lu against Marinko Matosevic and Federico Delbonis respectively.
