Argentine 10th seed Diego Schwartzman reached his third French Open quarter-final on Monday with a 7-6 (11/9), 6-4, 7-5 win over Germany's Jan-Lennard Struff.

Schwartzman will face 13-time champion Rafael Nadal or Italian teenager Jannik Sinner for a place in the last four. He was beaten by the Spaniard in last year's semi-finals.

The 28-year-old saved seven set points in the first set as he rallied from a 5-1 deficit against the 42nd-ranked Struff, who had only once before made the fourth round at a major.

Schwartzman let a 4-0 lead slip in the third set but held on to make his fifth Grand Slam quarter-final.
