WHOOP trackers removed for Alcaraz and Sabalenka as Australian Open enforces tournament approval
Alcaraz and Sabalenka ordered to remove WHOOP trackers at Australian Open amid policy confusion 2026.
Two world No. 1s were asked to remove WHOOP fitness trackers before going on court at the Australian Open. World No. 1 Carlos Alcaraz was stopped before his fourth-round match against Tommy Paul when an umpire noticed a WHOOP band tucked beneath a sweatband on his wrist. Aryna Sabalenka was also asked to remove her device before her first-round match.
WHOOP bands have become common among top players at this Australian Open. Launched in 2015, the low-profile, waterproof tracker is designed to be worn 24/7 to record metrics such as heart rate variability, sleep stages, skin temperature and blood oxygenation, and to help detect illness. The devices have been widely visible on players, coaches and staff as teams manage recovery during the tournament’s heat.
All WHOOP devices (3.0, 4.0, 5.0 & MG) have been approved for in-match use by the International Tennis Federation (ITF), and they have been permitted at WTA and ATP events for years, frequently worn under sweatbands. Under ITF rules the devices are allowed provided the player can show the haptic feedback is turned off or that the model lacks haptic feedback. The Australian Open, however, requires separate tournament-level approval before a device may be worn during a match.
WHOOP founder Will Ahmed reacted on social media: “Ridiculous. Whoop is approved by the International Tennis Federation for in-match wear and poses no safety risk,” Ahmed wrote on X. “Let the athletes measure their bodies. Data is not steroids.” Gear expert Jon Levey described WHOOP devices as “designed to monitor physiological markers throughout the day and their impact on the body’s readiness to perform… whether it be a tough three-setter or a tense day at the office.”
WHOOP issued a statement via a spokesperson: “WHOOP believes athletes have a fundamental right to understand their own performance and health—including during competition at events like the Australian Open. WHOOP is approved by the International Tennis Federation for in-match wear and poses no safety, fairness or competitive risk.
“Blocking access to personal health data does not protect sport. WHOOP will continue to stand with athletes and our members to defend their right to their data.”
The Australian Open has previously enforced a strict policy on wearables, most notably when Naomi Osaka was barred from wearing a connected TAG Heuer watch on court in 2022.

Medvedev weathers travel woes to rally past Rei Sakamoto at Miami Open
Medvedev overcame travel delays and a lost bag to rally past Rei Sakamoto on Stadium Court in Miami.
Daniil Medvedev endured travel setbacks before his Miami Open match but ultimately produced a steady recovery to defeat Rei Sakamoto, 6-7 (10), 6-3, 6-1. The former world No. 1 arrived at Hard Rock Stadium after a delayed luggage arrival and used patience and consistency to turn a precarious start into a decisive finish.
Medvedev had already faced disruption earlier in the Sunshine Swing, nearly missing the BNP Paribas Open after being stranded in Dubai. Those off-court headaches contrasted with a strong run on court: he came into Miami off a runner-up finish in Indian Wells. That event, usually noted for slow conditions that can frustrate Medvedev, proved favorable to him this year — he thrived in the California desert and even snapped Carlos Alcaraz’s 16-match winning streak en route to the championship match.
The slow conditions in Miami initially played into the hands of his opponent. Sakamoto, a 19-year-old IMG Academy alum, claimed a 22-point tiebreaker to take the first set and had Medvedev on the ropes. But Medvedev, seeded No. 9, steadied his game on Stadium Court and found a rhythm as the match progressed.
“It’s completely different conditions [here],” Medvedev said on court after the match. “It’s always been. Usually, I feel like it’s kind of quicker in Miami—not too much, but a bit. This year, it’s slower because Indian Wells was fast, so it feels much slower. The serve can still work but in the points it’s much slower. I was losing the rhythm and I was just not ready for the ball to react the way it was reacting.”
Medvedev said he sensed a drop in his opponent’s energy as the match lengthened. “I’m super happy I managed to build up moment and also the tiredness in him because he’s still a junior in a way,” he said after the match. “It’s not easy for him. He’s going to learn from this. So, I’m happy I managed to put it up and win the match.”

Tommy Paul’s Camo, Collabs and the Quiet Work of Returning to Form
Tommy Paul blends outdoor life, a New Balance collab and a patient return to top-level tennis. Now..
Tommy Paul has spent the early weeks of the season balancing a clear on-court mission with a life built around the outdoors and a pair of new shoes. “Being an outdoor kind of guy, I wear camo every single week if not every day,” Paul said, introducing the CT-Rally v2 “Outdoor Court” edition, his first colorway collaboration with New Balance.
“I think it’s the best-looking shoe on the market in tennis,” he said. Paul described New Balance as a partner that allows him style and expression. “They do what they want, and they do it well,” he told me. “They want to give me a platform to express myself and what I’m about.”
The apparel and equipment storyline sits alongside other outdoor projects. “It’s freedom, it’s meditation, but it’s also an escape,” Paul said of fishing and hunting. “Growing up in North Carolina, we’d be fishing every weekend I wasn’t playing in the summer. It was something I absolutely loved doing. I knew that, when I got older, I’d have that kind living where you go out there fishing, harvesting, and eating. It’s even cooler now because I’m in Florida and I can do it all year round.”
Paul also unveiled a partnership with Yellowfin Yachts, a new boat he enjoyed testing and joked about with peers. “That is so funny,” he said when I called it a “yacht.” He plans to travel in it, with the Bahamas on his short list.
The on-court narrative is straightforward. The 28-year-old former No. 8 halted his 2025 season after the US Open because of a foot injury that surfaced at Wimbledon, and he returned ranked No. 23. He pushed Carlos Alcaraz at the Australian Open, reached a final in Delray Beach and cites Davis Cup qualifying alongside Ethan Quinn and Emilio Nava as a season highlight. “I’m really just focused on right now, getting everything sorted and everything locked in to play my best tennis. If I’m playing my best tennis, everything will work itself out. I’m not really too focused on a No. 3 spot, Top 5 or Top 10 spot. I’m more focused getting to a point where I can play my brand of tennis consistently, without too much lapse. That’s what separates the top guys from the rest: even on their worst days, they figure out how to win a match. I think that’s something I’m really focused on.”
Off court, Paul has launched the Kids Outdoors Foundation with fiancée Paige Lorenze and worked with a Hobe Sound school. “They had a little basketball court, so we set up some tennis nets and spent some time with the kids, taught them a little tennis.”

A first-set tiebreak swung Auger-Aliassime’s way 7-3, and he closed the match in the second set with a late break to seal the 7-5 finish. The result provides a positive start to his run at a Masters 1000 tournament where winning early matches is often crucial to deeper progress.
The milestone underscores Auger-Aliassime’s consistency on the most common tour surface and highlights his capacity to win tight matches on big stages. As the Miami Open progresses, his form on hard courts will be watched closely by those tracking the season’s contenders.
