Paris - Swiss Roger Federer, seeded three, barely broke sweat in a 6-2, 6-3 dismissal of French wildcard Adrian Mannarino to reach the third round of the Paris Masters where he will face local favourite Richard Gasquet on Thursday.
Second seed Andy Murray started his campaign in ruthless fashion, beating France's Jeremy Chardy 6-2 6-4 to reach the third round.
World No 3 Murray, who withdrew from the Basel tournament because of injury, had little difficulty with Chardy, setting up a meeting with 13th seed Andy Roddick in the next round.
Briton Murray completed a stunning hat-trick of titles in as many weeks on the Asian swing of the ATP tour after winning the Shanghai Masters on October 16. He also won in Bangkok and Tokyo.
Serbian Janko Tipsarevic kept alive his slim hopes of making it to the ATP World Tour finals when the 11th seed thrashed American Alex Bogomolov Jr 6-1, 6-0 to reach the third round.
Tipsarevic, who needs to win the title if he is to grab one of the three remaining spots for the November 20-27 event in London, will next face Czech Tomas Berdych.
World No 1 Novak Djokovic also had too much for Croatian Ivan Dodig in a 6-4, 6-3 victory.
