Rafael Nadal moved into the third round of the Paris Masters with a straight sets victory over fellow Spaniard Marcel Granollers.
Nadal is appearing in Paris for the first time since 2009 having missed the last three years with injury, but the top seed looked to be feeling right at home despite being pushed to a 7-5 7-5 victory.
Nadal could manage just two breaks of serve, but crucially they both came at 5-5 in each set to enable him to then serve out on each occasion.
Granollers, who could only get in 58 percent of his first serves, forced just a single break point that Nadal saved, although he did make it hard work for the World No 1.
Nadal took an hour and 42 minutes to seal the victory, which sets up a third round meeting with Poland's Jerzy Janowicz.
World No.3 David Ferrer opened his Paris Masters title defence with a three-set win against Lukas Rosol.
The Spaniard, who enjoyed a first-round bye, came through 6-0 2-6 6-3 in one hour and 27 minutes at the Palais Omnisports.
Ferrer preyed on the inconsistency of Rosol's game, hitting 18 fewer unforced errors than his Czech opponent.
He will face 15th seed Gilles Simon in the third round after Simon saw off his fellow Frenchman Nicolas Mahut 6-4 6-7 (5-7) 7-6 (7-3) in a match lasting just short of three hours.
John Isner, a semi-finalist two years ago, will take on second seed Novak Djokovic in the third round after a 7-6 (7/3) 4-6 6-3 success against Polish qualifier Michal Przysiezny.
Isner, the 11th seed, fired 27 aces and 47 winners over the course of three tight sets.
Nicolas Almagro, the 12th seed from Spain, also made it through to the third round thanks to a 6-4 6-3 win against Croat Ivan Dodig.
Almagro's next assignment is against seventh seed Stanislas Wawrinka. The Swiss player, chasing a spot at the season-ending ATP World Tour Finals in London, was a 6-3 3-6 6-3 winner against Spanish left-hander Feliciano Lopez.
Fourth seed Juan Martin Del Potro, fresh from lifting the title at the Swiss Indoors on Sunday, defeated Croat Marin Cilic 6-4 7-6 (7/3).
Cilic, who sent down 19 aces, was playing in his first tournament since Wimbledon after serving a four-month doping ban.
