Alexander Zverev reached the French Open last 16 after coming through a nervy five-set thriller against Dutch 26th seed Tallon Griekspoor.
The German fourth seed trailed by a double break at 4-1 in the deciding set before winning 3-6 6-4 6-2 4-6 7-6 (10-3) on Saturday.
The victory came a day after a court case into domestic abuse allegations against Zverev began in Berlin.
The Olympic champion, who denies allegations of physically abusing his former girlfriend, does not have to be present in court and has remained in Paris for the clay-court major.
