Frances Tiafoe hadn’t dropped a set on the way to the French Open quarterfinals, but he wasn’t up to the task against Lorenzo Musetti.

Lorenzo Musetti escaped being disqualified from the French Open after accidentally kicking a ball at a line judge during this quarter-final win over Frances Tiafoe. The Italian progressed to his first Roland Garros semi-final after beating Tiafoe in four sets and will play defending champion Carlos Alcaraz on Friday for a place in the final.

Lorenzo Musetti advanced to his first semifinals appearance at the French Open Tuesday with a four-set win over Frances Tiafoe. Musetti held off Tiafoe despite receiving an unsportsmanlike conduct warning in the second set after inadvertently hitting a line judge with a ball he kicked toward the back wall at Roland-Garros out of frustration.
