Italy's Lorenzo Musetti serves to US Frances Tiafoe during their men's singles quarter-final match on day 10 of the French Open tennis tournament on Court Philippe-Chatrier at the Roland-Garros Complex in Paris. AFP
Eighth-seed Musetti won 6-2, 4-6, 7-5, 6-2 against the 15th seed after over two hours and 45 minutes of battle on Court Philippe Chatrier.
He next plays either defending champion Carlos Alcaraz of Spain or American Tommy Paul for a place in the final.
Musetti's serve proved to be a major weapon on the day as he fired down eight aces with an 81 percent success rate on his first serve in gusty conditions in Paris.
He also saved two of the three break points engineered by Tiafoe, who had 51 unforced errors to the Italian's 32.
Musetti has been one of the form players on clay this season, reaching at least the last four in all three of the principal warm-up events ahead of the French Open.
For both Musetti and world number 16 Tiafoe -- twice a US Open semi-finalist -- it was a first last-eight appearance at Roland Garros.
