Stanislas Wawrinka is through to the last 16 of the French Open for the third consecutive year after dispatching Gilles Simon in five sets.
The Swiss number two claimed a sloppy opening set 7-5 despite making 25 errors.
Although the pair shared six breaks of serve in sets two and three, both were closely fought and settled by tie-breaks in favour of Simon.
Wawrinka raised in game at the start of the fourth set and reduced his unforced error count remarkably, helping him to record a thrilling 7-5 6-7 6-7 6-3 6-2 win.
Jo-Wilfried Tsonga awaits Wawrinka in round four after the French number one beat Fabio Fognini in straight sets.
