Andy Murray held his nerve to beat France's Jeremy Chardy and reach his fifth French Open quarter-final.
The Scot, seeded third, came back from a break down in the third set to win 6-4 3-6 6-3 6-2 in two hours and 51 minutes.
He goes on to face seventh seed David Ferrer, who beat ninth seed Marin Cilic 6-2 6-2 6-4.
Murray, 28, has now won all 14 clay-court matches he has played in 2015.
The last time Murray failed to reach the quarter-finals at a Grand Slam was then he lost to Stan Wawrinka at the 2010 US Open.
Murray has an 12-1 win-loss record against players at their home Grand Slam. His only loss came against Gael Monfils at the 2006 French Open.
It is five years since he has fallen before the quarter-finals at a Grand Slam and nine years since he lost to a lower-ranked player than Chardy, the world number 45.
However, with the home crowd behind him on the raucous Court Suzanne Lenglen, Chardy threatened to cause a major upset as he levelled at one set all and broke early in the third.
The 28-year-old from Pau had only won one of his seven previous matches against Murray though, and 10 double-faults - several at key moments - particularly damaged his cause.
After breaks of serve were swapped in the first two games, Murray pumped his fist as he finished one terrific rally at the net on his way to moving 3-2 ahead.
Murray's defensive excellence helped close out spirited home favourite Chardy
The Briton had the contest in his grasp early in the second only for Chardy to fend off five break points, and urged on by the crowd he began to dictate.
A brilliant backhand return gave him an unexpected break for 3-1 and he saw out the set with 17 winners as Murray struggled to contain him.
Another backhand winner put Chardy a break up at the start of the third but his lead lasted only a few minutes, as a double-fault, a smash into the net and two loose groundstrokes handed it straight back.
With Murray relentlessly pressing on the return, the Frenchman offered up a ninth double fault to fall 5-3 behind and his hopes were slipping away fast.
Some breathtaking defensive work helped Murray grab the initiative early in the fourth and he broke three times to secure his 17th consecutive Grand Slam quarter-final place.
