MONTE CARLO (AFP) - Rafael Nadal and Roger Federer moved closer to a fourth final meeting at the Monte Carlo Masters on Thursday as both posted straight-set third round wins to coast into the quarter-finals. Third seed Andy Murray, meanwhile, drew jeers for drop shots against an injured opponent, with the Scot shunning the popularity contest in his 6-3, 6-3 defeat of French 16th seed Gilles Simon. The win was the second in as many days for Murray, who had lost a career-worst four straight matches over the last two months without winning even a set. Next contest will come against a surprise opponent after world number 82 Frederico Gil of Portugal stunned Gael Monfils 7-6 (7/2), 6-2 to leave French seeds 0-3 on the day. Top seed Nadal, a consecutive six-time champion who is now unbeaten in 34 straight matches in the principality, maintained his traditional momentum to see off Frenchman Richard Gasquet 6-2, 6-4. Three-time losing finalist Federer, the number two seed, was equally ruthless as he dispatched Croatian Marin Cilic 6-4, 6-3 in 71 minutes with a break of serve per set enough to see him through. Federer won his 24th match of the season for four defeats -- his last to Nadal in Miami, the other three to Novak Djokovic. He now stands level with Djokovic for the most wins so far this season. Nadal took 93 minutes to claim what was his eighth win without a loss against 18th-ranked Gasquet.
