An off-colour Carlos Alcaraz had to dig deep to beat inspired qualifier Jesper de Jong and reach the French Open third round.
Spain's Alcaraz looked subdued at times in a 6-3 6-4 2-6 6-2 victory over a player ranked 173 places below him.
Dutchman De Jong played well above his ranking but it was a rusty performance from Alcaraz, who had to twice come back from a break down in the fourth set.
"I prefer not to spend too much time on the court, I want to be in good shape for the next round but every match is different," Alcaraz said.
