Paris, France (SportsNetwork.com) - Former champion and four-time runner-up Roger Federer was a comfortable third-round winner Friday at the French Open.

The second-seeded former world No. 1 great handled Bosnian Damir Dzumhur, 10 years the iconic Swiss' junior, 6-4, 6-3, 6-2 on the famed red clay on Court Chatrier.

"I didn't know him and I didn't know how he'd play on the key points," Federer said.

The 33-year-old Federer is through to the fourth round at Roland Garros for the 11th straight year. He completed the career Grand Slam when he lifted the trophy here in 2009, beating Swede Robin Soderling in the final.

The world No. 88 Dzumhur was contesting the third round of a Grand Slam for the second time this year, having also reached the last 32 at the Australian Open as a qualifier.

"I guess it was entertaining," said Dzumhur. "I really was excited before the match."

In addition to his title here, the 17-time Grand Slam king Federer lost to Rafael Nadal in four Roland Garros finales.

Federer's fourth-round opponent will be 13th-seeded French favorite Gael Monfils, who outlasted 21st-seeded Pablo Cuevas of Uruguay 4-6, 7-6 (7-1), 3-6, 6-4, 6-3 in 3 hours, 23 minutes in Friday's final result.

Federer is 3-0 versus Monfils at the French: a semifinal win in 2008, a quarterfinal victory in 2009, and another quarterfinal win in 2011.

Meanwhile, fourth-seeded former Wimbledon runner-up Tomas Berdych of the Czech Republic got past France's Benoit Paire 6-1, 6-7 (5-7), 6-3, 6-4 and eighth- seeded former Australian Open champ Stan Wawrinka of Switzerland handled American Steve Johnson, 6-4, 6-3, 6-2, leaving the men's draw with only one American, Jack Sock.

Next up for Berdych will be 14th-seeded Frenchman Jo-Wilfried Tsonga, while Wawrinka will play 12th-seeded Frenchman Gilles Simon.

An all-French battle on Day 6 saw Simon outlast marathon man Nicolas Mahut 6-2, 6-7 (6-8), 6-7 (6-8), 6-3, 6-1 in 3 hours, 47 minutes. Mahut played in the longest-ever tennis match in 2010 when he lost to American John Isner in just over 11 hours in a Wimbledon bout that was played out over three days, including an absurd 70-68 fifth set.

Tsonga charged on by handling Spaniard Pablo Andujar 7-6 (7-3), 6-4, 6-3.

The second round concluded when 20th-seeded Frenchman Richard Gasquet held off Argentine Carlos Berlocq 3-6, 6-3, 6-1, 4-6, 6-1 in a match that was suspended after four sets on Thursday because of darkness. Gasquet's third-round opponent will be 15th-seeded South African slugger Kevin Anderson.

Another third-round result saw Russian journeyman Teymuraz Gabashvili douse Czech Lukas Rosol 6-4, 6-4, 6-4. Gabashvili will face fifth-seeded U.S. Open runner-up Kei Nishikori of Japan on Sunday.

Several stars will take to the courts for third-rounders on Saturday, including world No. 1 Novak Djokovic, third-seeded Aussie Open runner-up Andy Murray and the sixth-seeded former top-ranked great Nadal. Djokovic will take on Aussie teenager Thanasi Kokkinakis, while Murray will meet 29th-seeded Aussie Nick Kyrgios and Nadal will be opposed by Russian Andrey Kuznetsov.

The eight-time major champion Djokovic still needs a French Open title to complete the career Grand Slam. He currently holds the Aussie Open and Wimbledon crowns.

Djokovic lost to Nadal in two of the last three French Open finals, including last year.

The two-time Grand Slam champion Murray is a perfect 12-0 on clay this year. The 14-time major titlist Nadal is a nine-time French Open champ, including five straight wins in Paris from 2010-14 and four straight crowns from 2005-08.

Also on the Day-7 schedule will be seventh-seeded former Roland Garros finalist David Ferrer and ninth-seeded U.S. Open champ Marin Cilic. Ferrer will take on Italian Simone Bolelli, while Cilic will encounter 23rd- seeded Argentine Leonardo Mayer, a clay-court runner-up in Nice last week.
