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.

Carlos Alcaraz was almost unrecognizable when he stepped on the court against Reilly Opelka for his first-round match the US Open. His usual bushy, mop haircut was replaced by an unexpected buzz cut as a result of a pre-game mishap involving his brother.

That wasn’t all Alcaraz showed off to McIlroy, however. After his first-round victory over American Reilly Opelka, Alcaraz celebrated by demonstrating his golf swing to McIlroy, who was watching on above. Check it out.
