David Ferrer and Jo-Wilfried Tsonga were easy winners Sunday in the fourth round of the French Open.

The fourth-seeded Ferrer needed an 1 hour and 45 minutes to dispatch South Africa's Kevin Anderson, 6-3, 6-1, 6-1, while the sixth-seeded Tsonga had little trouble in a 6-3, 6-3, 6-3 pasting of Serbia's Viktor Troicki.

Ferrer, a semifinalist last year at Roland Garros, has not dropped a set in four matches this week. The Spaniard broke serve six times on Sunday and saved both break points against his serve. Anderson committed a whopping 41 unforced errors to Ferrer's 11.

"I'm very happy with my game today," said Ferrer. "Maybe I played the best match of this week. I am in the second week of the Grand Slam, and now I want to rest and to be focused on the next match."

Next up for Ferrer will be countrymate Tommy Robredo, who for the third straight match rallied from a two-set deficit. The veteran on Sunday beat fellow Spaniard Nicolas Almagro, 6-7 (5-7), 3-6, 6-4, 6-4, 6-4, after also roaring back to beat Igor Sijsling in the second round and Gael Monfils in round three.

Robredo, seeded 32nd, had missed the French Open each of the last two years because of injuries and earlier in 2013 earned his first win in two years with a title at Casablanca. The former world No. 5 has matched his farthest Grand Slam run, with prior quarterfinal appearances at the French Open in 2003, 2005, 2007 and 2009, along with a round of eight result at the Australian Open in 2007.

Tsonga, the winner in Marseille earlier this year, is into the quarterfinals at his home Slam for the second straight year. The Frenchman will face the winner between countrymate Gilles Simon and Roger Federer. He lost to Federer in the Australian Open quarterfinals back in January.
