French No.1 Ugo Humbert defeats Italian Lorenzo Sonego 5-7, 6-3,6-1. The Frenchman had never won a match in the main draw of Monte-Carlo before.

He is the last Frenchman still in the running to reach the semi-finals. He will play Norwegian Casper Ruud (10th), double finalist at Roland-Garros, on Friday. The Italian, beaten in the second round of qualifying, was drafted at the last moment to replace Carlos Alcaraz who announced his withdrawal due to injury on Tuesday. As a result, the Italian entered the fray in place of the world No.3 and beat the Canadian Félix Auger-Aliassime before meeting HumberT in the round of 16. The French No. 1 won five games in a row to equalize at one set everywhere and come away 2-0 in the decisive set. Then he achieved the double break to lead 4-1 and no longer gave the Italian the slightest chance.
