Former champion Roger Federer handled Spanish qualifier Pablo Carreno-Busta as the French Open swung into action Sunday in Paris.
Federer cruised past Carreno-Busta by a 6-2, 6-2, 6-3 margin in 80 minutes on the famed red clay at Stade Roland Garros.
The Swiss superstar fired 10 aces past Carreno-Busta, who was making his Grand Slam debut after winning seven consecutive Futures events.
Federer, who has yet to win a title of any kind in 2013, captured the 2009 French Open crown -- the only one Rafael Nadal hasn't won in the last eight years -- to complete a career Grand Slam.
The 31-year-old Federer, who owns 17 Grand Slam titles, will take on either Somdev Devvarman or Daniel Munoz-De La Nava in the second round.
Canadian Milos Raonic, the No. 14 seed, fired 16 aces past Belgian Xavier Malisse en route to a 6-2, 6-1, 4-6, 6-4 victory.
Other wins from seeded players came from Frenchman Gilles Simon and South African Kevin Anderson. The No. 15 seed Simon rallied past former world No. 1 Lleyton Hewitt by a 3-6, 1-6, 6-4, 6-1, 7-5 margin and the 23rd-seeded Anderson handled Illya Marchenko 6-3, 7-5, 6-4.
Meanwhile, Joao Sousa defeated Go Soeda 6-1, 6-3, 6-2, Roberto Bautista Agut took down Gilles Muller 6-3, 6-4, 6-2 and Blaz Kavcic beat James Duckworth 6-2, 6-2, 6-2.
Nadal beat Novak Djokovic in last year's final to claim a third straight and Open Era-record seventh overall men's French Open title.
