Paris, France (SportsNetwork.com) - Roger Federer, Stan Wawrinka and Kei Nishikori were easy men's winners on the first day of play at the 2015 French Open.

Federer, the 2009 champion and this year's second seed, cruised to a 6-3, 6-3, 6-4 victory over Colombia's Alejandro Falla, while fellow Swiss star Wawrinka had little trouble in a 6-3, 6-2, 6-3 romp over Marsel Ilhan of Turkey. The fifth-seeded Nishikori also advanced in a 6-3, 7-5, 6-1 triumph over Frenchman Paul-Henri Mathieu.

Wearing pink shorts and a purple shirt, Federer was not broken on Sunday in a match that lasted just under two hours. He broke for a 5-3 lead in the first set, then broke serve twice in the second before finishing the match with one more break to improve to 8-0 all-time against Falla.

"I like the outfit. Let's enjoy color while we can," said Federer in a nod toward Wimbledon. "It's good to try to be fashionable in a city like Paris. You always want to make a statement. I think people enjoy it. I think it's powerful. We will see how many times I can wear it -- I hope seven matches."

Federer had his most uncomfortable moment after the match concluded, as a fan managed to run onto the court and tried to take a selfie with the 17-time Grand Slam champion.

"I'm not happy about it," said Federer, who said a similar incident occurred on Saturday as well. "Obviously not one second I'm happy about it. It happened yesterday in the practice, too."

Wawrinka, who could face Federer in the quarterfinals, made sure there was no repeat of last year when he fell in the first round at Roland Garros.

"I draw the lessons from my elimination last year, so I handled the match differently," said Wawrinka. "It's a new year, it's a new tournament, it's a new season, it's a new French Open."

Other early men's winners on a limited schedule Sunday included French crowd favorite Jo-Wilfried Tsonga, Spain's Roberto Bautista Agut, Germany's Philipp Kohlschreiber and Ernests Gulbis of Latvia.

The 14th-seeded Tsonga pounded Swedish qualifier Christian Lindell, 6-1, 6-2, 6-2, while Bautista Agut, seeded 19th, eased past Germany's Florian Mayer, 6-3, 6-1, 6-3. The 22nd-seeded Kohlschreiber dropped just three games in a rout of Japan's Go Soeda and the 24th-seeded Gulbis picked up a 6-4, 6-4, 7-6 (7-3) win over Dutch veteran Igor Sijsling.

All but one of the 16 men's matches Sunday were decided in straight sets. The lone exception went the distance, as American Steve Johnson outlasted Spain's Guillermo Garcia-Lopez.

The 26th-seeded Garcia Lopez rallied from a two-set deficit to force the fifth, but wilted down the stretch as Johnson earned a 6-3, 6-3, 6-7 (1-7), 3-6, 6-3 victory.

One other minor upset saw Marcos Baghdatis of Cyprus eliminate 25th-seeded Ivo Karlovic in straight sets. Baghdatis will next play Bosnia's Damir Dzumhur, who advanced when Russian veteran Mikhail Youzhny was forced to retire after two sets.

Frenchman Nicolas Mahut, Lukas Rosol of the Czech Republic, Serbia's Dusan Lajovic, Israel's Dudi Sela and Spaniards Pablo Andujar and Marcel Granollers were among the unseeded winners Sunday. Granollers is up next for Federer in round two, while Lajovic earned a second-round date with Wawrinka.

The first round continues Monday with Andy Murray, Tomas Berdych and Frenchmen Gilles Simon and Gael Monfils on the schedule.

Murray will carry a 10-0 mark this year on clay into the tournament. The third-seeded Scot won his first two career clay titles in Munich and Madrid earlier this spring, stunning many with a victory over Rafael Nadal at the Magic Box. He will play Argentina's Facundo Arguello on Monday.

Berdych, seeded fourth, will meet Japan's Yoshihito Nishioka, while Simon and Monfils will each face countrymen on Monday. The 12th-seeded Simon will take on Lucas Pouille and the 13th-seeded Monfils will square off against Edouard Roger-Vasselin.
