Ahead of the Spaniard's first fixture in the 2025 U.S. Open, Alcaraz cut off all his hair, and is now rocking a bold buzz-cut look. Alcaraz is slated to play American Reilly Opelka in the first round Monday night, and is vying for his second career U.S. Open title after previously winning it in 2022 when he was just 19 years old.

After impressing in a 6-4 7-5 6-4 victory, Alcaraz quizzed the crowd on his new look, earning loud cheers when he said: "I've got to ask to the people if they like the new haircut or not. Do you like it guys? I think they like it."

On the court, Alcaraz seemed unfazed by the added attention from his haircut. He needed just over two hours to see off the towering, big-serving Opelka in Arthur Ashe Stadium and kick off his pursuit of a sixth grand slam title and second at the US Open.
