American Frances Tiafoe’s hopes of reaching his first semifinal at Roland Garros came to an end against Italy’s Lorenzo Musetti on Tuesday.

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.
