Carlos Alcaraz surprised many with his new close-cropped buzz cut ahead of his first-round US Open match. On Monday, August 25, before the Spaniard arrived for his first-round match against Reilly Opelka at Arthur Ashe Stadium, he was asked about the reason behind sporting a new look.According to Feliciano López on ESPN, Alcaraz underwent a haircut, but it didn't go well, so he asked his brother, Alvaro, to shave his head. Alcaraz was on his way to dyeing his hair blonde."I got a haircut that didn't turn out very well, and I had to shave it all off," Alcaraz said.About Carlos Alcaraz's buzz cut, fellow tennis star Frances Tiafoe had a hilarious reaction. He said:“Yeah, it’s horrible. It's terrible. He’s my guy though. It’s funny. I looked at him and I was like: ‘I guess you’re aerodynamic.’ Juan Carlos ‘Mosquito’ was laughing. He was like: ‘Yeah, he’s faster than he already was.’ I was like: ‘Well, that’s a problem.’ I don’t know who told him that it’s good. I don’t know who told him to do that, but it’s terrible."“From a guy who gets haircuts week-in, week-out, and prides myself on good haircuts, it’s horrendous. At the end of the day, it’s Carlos, and that’s my guy. But yeah, he needs to get with me. He needs to get with me for sure,” he added.Alcaraz began his championship campaign against big-serving Reilly Opelka. The match is currently underway, with the Spaniard leading 4-2 in the first set.Carlos Alcaraz reveals he's done with sponsor-related events at the US OpenBefore Carlos Alcaraz turned up for his first-round match against Reilly Opelka, he was interviewed by Vogue.
