Defending champion Rafael Nadal reached his 11th French Open semi-final after ruthlessly turning around his rain-delayed quarter-final against Argentine 11th seed Diego Schwartzman.
Top seed Nadal, 32, trailed 6-4 3-5 when play was halted on Wednesday.
The world number one, bidding for a record-extending 11th title, clinched the second set soon after the restart.
And he lost just four games on Thursday on his way to a 4-6 6-3 6-2 6-2 victory.
The Spaniard will face either Marin Cilic or Juan Martin del Potro, whose unfinished quarter-final was also moved over to Thursday, in Friday's semi-final.
