On Sunday, Rory McIlroy was complimenting Carlos Alcaraz's new haircut. On Monday, Alcaraz mimic'd McIlroy's golf swing after his first-round win.

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

Leave it to Carlos Alcaraz to create more buzz with his haircut than most players do with their entire first-round performance. The Spanish sensation rolled into Flushing Meadows sporting a fresh buzz cut that had everyone from Rory McIlroy to Frances Tiafoe weighing in like they were judging a hair show instead of watching tennis.
