Patrick Mouratoglou has broken down the adjustments Carlos Alcaraz has made to his serve and assessed whether the move has been a success so far.

Alcaraz made a change to his serve technique and adjusted his racket specifications during his preparations for the 2025 season.

During the Australian Open, the four-time Grand Slam winner spoke about the importance of making tweaks.

“Of course, you have to change things. Jannik [Sinner] has said the same thing, that he changed things in the pre-season that perhaps we can’t see, but he feels that they’re different,” the world No 3 said.

“To always be at the top you have to keep adapting to what’s demanded of you and changing little things to be better or just as competitive.”

On his new serve, Alcaraz explained: “We knew that the serve was something I had to improve, we had to do something. It had to be more accurate and I wasn’t managing to do that.

“The new movement is a little more relaxed, quite a lot more relaxed, with a looser wrist to try and improve my timing and there’s no pause when the racquet gets to the top, it’s all more fluid.

“That also affects a few things during matches, for example, I’m not so tense, which can take its toll physically.”

In a post on his Instagram account, Mouratoglou analysed Alcaraz’s new service motion as he looked at an image comparison of the Spaniard serving at the Australian Open in 2024 and 2025.

“I see two things on that photo of Carlos Alcaraz,” said the Frenchman, who currently coaches Naomi Osaka having previously worked with Serena Williams, Stefanos Tsitsipas and Holger Rune.

“First thing, the right leg which is going so far up, and the second thing I see is his left arm, which is going so far back also after the serve.

“What does it say? It says one big thing, how loose he is, how relaxed.

“There is no muscular tension that prevents his leg from going so far back and high.

“There is no muscular tension that prevents his left arm from going far to the left.

“How good is it? It’s great. If you want to create power, you need looseness. That’s one of the reasons why he has so much power in his game.

“I like the left arm because I’ve always said it’s very important to let the left arm go to the side when you serve because it creates natural rotation of the body, and natural rotation of the body creates natural power. You need that rotation.”
