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.

ATP Italian Open Masters

Djokovic’s delayed clay return in Rome and what it reveals about his 2026 season

Djokovic makes a late Rome clay start after a March exit and a Miami withdrawal. Missed three events.

Novak Djokovic returns to the clay swing this week at the Internazionali BNL d’Italia, marking his latest European clay-court start outside of the COVID-19-shifted 2020 schedule. The six-time Rome champion is seeded No. 3 and landed in the same half of the draw as Alexander Zverev.

Djokovic missed the 2025 edition at the Foro Italico, ending a run of 18 consecutive main-draw appearances. The 38-year-old most recently competed in March, when he was edged out in the fourth round of the BNP Paribas Open by Jack Draper. He cited a right shoulder injury for his subsequent withdrawal from the Miami Open, a decision that began a stretch in which he missed three Masters 1000 events.

This delayed arrival in Rome is notable for Djokovic: on four occasions his season-opening appearance on clay has culminated in a title. A year ago, after opening losses in Monte Carlo and Madrid, he captured his 100th tour-level title at Geneva and followed that with a semifinal showing in Paris.

The backdrop to Djokovic’s return includes Jannik Sinner arriving off another ATP Masters 1000 triumph as he heads into his Rome homecoming. Djokovic halted Sinner’s bid for a third successive Australian Open title in January. After dropping his Doha quarterfinal to Jakub Mensik, Sinner has since compiled a 23-match win streak and surpassed 14,000 rankings points for the first time.

With Rome the final opportunity to influence Roland Garros seedings, the ATP Top 5 remains unchanged heading into the tournament. Carlos Alcaraz is out for the clay swing with injury, and the players positioned to benefit for crucial seed bumps are No. 3-ranked Alexander Zverev and No. 5-ranked Felix Auger-Aliassime. Zverev did himself a favor by reaching the Mutua Madrid Open final, widening his lead over Djokovic to 1,105 rankings points. Zverev also has 200 points to defend from his 2025 Rome quarterfinal result.

Rome Day Preview: Blockx, Pliskova and Prizmic in the spotlight

Blockx’s rise, Pliskova’s comeback bid and Prizmic’s breakout headline Rome’s opening matchups..

Alexander Blockx has emerged as a compelling presence on tour this spring. The 21-year-old from Belgium reached the semifinals in Madrid last week and now sits at No. 36 in the rankings. That rise has not been enough to earn a seed in Rome, though he should make the cut at the Slams. In Rome he faces a different sort of challenge: a younger opponent. Cina, a 19-year-old from Palermo who reached as high as No. 4 in the juniors, will have local support. As a pro, however, Cina has not been ranked higher than No. 183. Blockx’s profile fits the modern top-level ATP player: a 6’4 frame, a strong serve, a heavy topspin forehand and a two-handed backhand. Winner: Blockx

Karolina Pliskova’s return to the later rounds of a WTA 1000 event was unexpected at the start of the year. The 34-year-old finished 2025 ranked outside the Top 1000 and had not advanced past the second round at a major since 2023. Last week in Madrid she looked more like the player who once held No. 1 in the world, making the quarters and coming within a set of the semifinals. Now at No. 130, Pliskova has momentum and tournament history on her side: she won this event in 2019 and reached the final in 2020 and 2021. She opens against Bouzas Maneiro, a fiery 23-year-old from Spain ranked 50th. They have never played each other. Winner: Pliskova

Dino Prizmic is another name that surfaced during Madrid. The 20-year-old from Croatia, listed at 6’2, plays with noticeable grit and physicality. He recorded eye-opening wins over Matteo Berrettini and Ben Shelton last week in Madrid, moves to a career-high No. 79 and is now a player to watch as the clay season progresses. His rise this spring has been rapid and memorable.

Wawrinka to Close Career with Basel Tribute after Rome Withdrawal

Three-time major champion Stan Wawrinka will bring his farewell season to a close on home soil in October, the Swiss Indoors Basel has indicated.

The tournament announced plans for a special evening on Monday, October 26 at 6 p.m., with a pre-sale launching Wednesday. “An emotional evening full of memories, surprises and magical moments from the career of the Vaud-born superstar awaits spectators,” organizers teased. The statement also made clear the end point of his farewell season: “He would have liked to keep playing forever. But Basel marks the end of the line for Stan Wawrinka as he says goodbye to the game,” the tournament wrote.

Wawrinka began his final season with encouraging signs, competing at the United Cup and reaching the third round of the Australian Open. The 41-year-old returned to the Top 100 in February and March before falling back in the rankings and missing the initial Roland Garros main-draw entry cutoff. He remains due to be recognized following his last French Open match.

Preparations for Paris suffered a setback when Wawrinka withdrew from his second-round qualifying match in Rome. According to the entry, back pain prevented him from taking on Pablo Carreño Busta, forcing an early end to his bid in the Italian event.

The Basel tribute is presented as a final, formal farewell on the site where Wawrinka will end his professional career. Organizers promise an evening that reflects on the highlights of his time on tour and affords fans a chance to celebrate the Vaud-born star before he departs the tour.
