Top seed Novak Djokovic's quest for a second career Grand Slam continued with another one-sided victory as he reached the French Open last 16.
The 2016 champion, aiming for a 19th Grand Slam, took six of nine break points and did not face one himself.
Djokovic's next opponent will be rising Italian teenager Lorenzo Musetti.
Musetti, 19, is playing in the main draw of a Grand Slam for the first time and went through to the fourth round by beating compatriot Marco Cecchinato in an entertaining contest where the pair hit a combined 106 winners.
Two audacious winners from Musetti - a behind-the-back volley and a flicked lob after he scampered back to the baseline - were particularly special as he won 3-6 6-4 6-3 3-6 6-3 in his first five-setter.
