Carlos Alcaraz was already the men's favorite at the 2025 Wimbledon Championships, but the Spaniard could be even tougher to beat because of a piece of equipment he is using.

Alcaraz is again in the fourth round at SW19 after defeating Jan-Lennard Struff in four sets. Although the German provided a reasonable test, it always felt like the match was on the two-time defending champion's racket.

Conditions in London have been warmer than usual at Wimbledon. The opening day was the hottest ever recorded at the iconic tournament, and fans and players had to take action to stay cool and hydrated.

All players have measures they use to counter hot weather. However, one of Alcaraz's is a more high-tech way of making sure he is dealing with the conditions compared to anyone else in the draw.

Alcaraz has been wearing a blue patch called the SweaTracker on his chest to monitor his sweat and hydration levels. That ensures the Spaniard is getting the ideal level of hydration to stop himself from being hampered in any way.

This is not the first tournament in which Alcaraz has used the technology. He also did so against Jannik Sinner in their incredible 2025 final, which Alcaraz won after saving three championship points in the deciding.

That extraordinary battle lasted 5 hours and 29 minutes, making it the lengthiest final in Roland Garros history. Alcaraz must have been particularly grateful to have the technology monitoring his sweat and hydration levels during such a grueling match.

When speaking about the chest patch, Alcaraz highlighted how it might only make a minor difference to him but that any small thing can be crucial when trying to win the most significant tournaments in the world.

"I always say that details make the difference. Yes, it's something to control sweat, to know what I should take during matches, before matches, to be at 100%. It probably only helps me one or two percent more. But I believe, as I said, that details make the difference. It's something I work on sometimes. I did it in Paris. I use it here to see what I should take."

The technology was developed by a firm called Sweanty. The SweaTracker is expected to be commercially released sometime next year, and athletes like Alcaraz are able to use it before the general population.

Alcaraz might need any advantage he can get to win a third Wimbledon title. Sinner and Novak Djokovic, projected to meet in the semifinal, are playing superb tennis, making either of them a formidable challenge in the final.

Nonetheless, the ATP world No. 2 will be rightly confident of winning another Wimbledon crown. He has undoubtedly been the best grass-court player since 2023, and a special performance might be needed to stop him.

Others are going through a more challenging time. Stefanos Tsitsipas retired in the opening round at Wimbledon, and his new coach, Goran Ivanisevic, tore into his fitness and professionalism afterward, calling it the worst he has ever seen.
