Carlos Alcaraz is causing as stir after photos of the young Spaniard shirtless during practice for the US Open appeared online over the weekend.

The 19-year-old reached the quarter-finals in New York last year and is currently No.4 in the ATP rankings.

“I’ve worked really, really hard to be ready,” Alcaraz said.

“I feel ready physically and mentally, you know. Yeah, I feel great. I feel ready.

“Of course, the goal for this US Open is to try to reach the semifinal to reach one more round of a Grand Slam. So I am going to try to go for it. I feel great.”
