Former champion Roger Federer and David Ferrer won their respective first-round matches as the French Open swung into action Sunday in Paris.
Federer cruised past Spanish qualifier Pablo Carreno-Busta by a 6-2, 6-2, 6-3 margin in 80 minutes on the famed red clay at 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 India's Somdev Devvarman in the second round. Devvarman handled Spaniard Daniel Munoz-De La Nava 6-3, 6-3, 7-5.
Ferrer, a semifinalist last year, moved on with a 6-4, 6-3, 6-4 victory over Australia's Marinko Matosevic.
The fourth-seeded Spaniard maintained his record of always reaching at least the second round here. He is playing in his 11th consecutive French Open.
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, while 18th-seeded American Sam Querrey beat Slovak Lukas Lacko 6-3, 6-4, 6-4.
Other seeded winners included Frenchmen Gilles Simon and Jeremy Chardy, Italian Andreas Seppi 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, the No. 20 seed Seppi outlasted Argentina's Leonardo Mayer 6-7 (4-7), 6-4, 6-3, 6-7 (2-7), 6-4, the 23rd-seeded Anderson handled Ukrainian Illya Marchenko 6-3, 7-5, 6-4 and the 25th-seeded Chardy got past German Benjamin Becker 6-4, 6-2, 7-5.
Also posting wins on Day 1 were Frenchman Michael Llodra, Serbian Viktor Troicki, Portugal's Joao Sousa, Spaniard Roberto Bautista Agut, Slovenia's Blaz Kavcic and Czech Jan Hajek.
One match was suspended due to darkness, with Marcel Granollers, the 31st seed, and fellow Spaniard Feliciano Lopez tied at two sets apiece.
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.
