Spanish tennis player Carlos Alcaraz debuted a buzzed haircut at the 2025 U.S. Open, a dramatic change from his usual thick hair. He explained that the haircut was the result of a misunderstanding with his brother, who accidentally cut it shorter than intended. Alcaraz acknowledged the new look was quite different but said he felt his hair was too long before the tournament. The haircut attracted considerable attention and commentary, including from former tennis star Maria Sharapova, who noted its low maintenance. Alcaraz began his U.S. Open campaign with a straight-sets victory over American Reilly Opelka, winning 6-4, 7-5, 6-4 in the first round. After the match, Alcaraz celebrated by demonstrating a golf swing in front of Rory McIlroy, the world No. 2 golfer, who was in attendance. The interaction between the two athletes, both ranked No. 2 in their respective sports, was highlighted during the event. Alcaraz asked the crowd if they liked his new haircut, receiving a positive response. His new look and first-round win at the U.S. Open have been widely covered by sports media.
