Asked whether playing the French Open, Wimbledon and the Olympics over the past few months caused him to enter the U.S. Open with less energy than he had in previous years, Carlos Alcaraz responded: “Probably. Yeah, the tennis schedule is so tight. I’ve been playing a lot of matches lately, you know, with Roland Garros, with Wimbledon, Olympic Games.

“I took a little break after the Olympic Games. I thought it was enough. It was really helpful for me. Probably it wasn’t enough.

“But, yeah, probably I came here with not as much energy as I thought that I was going to come. But, I mean, I don’t want to put that as excuse.

“Yeah, it’s so tight. Probably I’m a guy or I’m a player that needs more days or more break coming into the good tournaments or the important ones. So I have to think about it, and I have to learn about it. That’s it.”
