Overview
- Carlos Alcaraz was told mid‑match to remove a Whoop band, with reports that Jannik Sinner and Aryna Sabalenka were also instructed to take theirs off.
- Grand Slams operate under a different rulebook than the ATP and WTA, which have approved in‑match wearables since 2024 and 2021 respectively.
- Whoop founder Will Ahmed criticized the removals as “ridiculous” and urged that players be allowed to measure their bodies.
- Ahmed said Whoop is shipping its discreet ‘Body’ undergarment line to players so devices can be worn in clothing during matches.
- He cited ITF guidance indicating Whoop can be worn safely in competition, as debate grows over athlete access to biometric data such as heart rate, sleep, stress and recovery.
