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.

Frances Tiafoe had a look of shock and bewilderment on his face when he came off the court at Arthur Ashe Stadium.

Even golf star Rory McIlroy was surprised to see tennis sensation Carlos Alcaraz sporting a new look at the US Open.
