Defending champion Carlos Alcaraz won the French Open finals back to the final after early fears of eighth-time seed Lorenzo Musetti, who was eventually forced to retire due to injury.
Italy's Musetti scored 6-4 and 6-0 for the next two sets 6-4 and led 2-0 on the fourth time before his opponent's leg injury was held on Friday.
After Rafa Nadal and Gustavo Kuerten, the Spaniard is trying to be the third man of the century, facing world No. 1 Jannik Sinner or 24-time Grand Slam champion Novak Djokovic in Sunday's final.
"It's never been a great experience," Alcaraz said.
“He’s a great player and his Claycott season has been incredible…I hope he recovers quickly and I’m sure we’ll enjoy his tennis soon.”
Musetti twice denied Alcaraz had a chance to break in nine games of the opening ceremony, before the 23-year-old suddenly dialed out the intensity and snatched the opening ceremony when his Spanish opponent made a mistake in a bad service match.
Frustrated Alcaraz kicked his bench in the second set but finally found the path to Musetti's tenacious defense, reaching level after the tiebreaker, and then producing a dazzling power and precise performance to eliminate the bagel in the third set.
Musetti appeared to be blocked by the left thigh from her left thigh midway through the third set, throwing a towel after two games in the fourth game.
"The first two sets were tough. I had a chance to play but couldn't make the most of the game," Alkaraz added.
“When I won the second set, I felt relieved that I knew I needed to be aggressive and be myself. I was calm. I could see clearer and play great tennis at the start of the third time.
"I feel good physically. It's been three weeks, but I have one more step to take. I'm great to play tennis and I'm confident. I've been doing a great job in this game and it's time to give 100% in the final."
Alcaraz said he would adjust Philippe Chatrier's second semifinal to study his potential opponents.
"I won't miss the game tonight, it's one of the best games we can have right now, the Sinners vs Djokovic," he said.
“I’m going to see it and enjoy it and take the tactics from the game.”
