Reigning champion Carlos Alcaraz reached the French Open final as Lorenzo Musetti retired injured from their last-four tie on Friday, ahead of world number one Jannik Sinner's clash with 24-time Grand Slam champion Novak Djokovic.
World number two Alcaraz was leading 4-6, 7-6 (7/3), 6-0, 2-0 in the fourth set under the Court Philippe Chatrier roof when Italian Musetti called it quits due to an apparent thigh injury.
