As the clay courts of the Caja Mágica hummed with anticipation for the 2025 Mutua Madrid Open, Alexander Zverev, the world’s second-ranked tennis player, arrived in the Spanish capital not only as the top seed but as a vocal critic of the sport’s anti-doping protocols. Fresh off a morale-boosting title run in Munich, the 28-year-old German used his pre-tournament press conference to air his frustrations, declaring the doping process “annoying” and calling for reforms to respect players’ personal lives. His candid remarks, including a personal anecdote about his young daughter, have reignited debates about balancing clean sport with athletes’ basic freedoms, casting a spotlight on a system under scrutiny after high-profile cases involving Jannik Sinner and Iga Swiatek.
Zverev’s critique comes at a time when tennis is grappling with the fallout from doping controversies. Sinner, the world number one, is serving the final days of a three-month ban for testing positive for clostebol in 2024, a case attributed to contamination from a physiotherapist’s spray. Swiatek, the women’s world number two, faced a one-month suspension last year after a positive test for trimetazidine, linked to contaminated melatonin. These incidents have thrust anti-doping procedures into the headlines, prompting Zverev to reflect on their impact. “I think it’s just a subject that we’ve been talking about more over the last half a year or so, because of, obviously, Jannik and Iga a little bit,” he said, noting that while protocols haven’t changed, their invasiveness remains a sore point.
The heart of Zverev’s grievance lies in the rigid “whereabouts” rule, which requires players to designate a daily one-hour window for testing, 365 days a year. Failure to comply risks a “missed test,” and three misses can lead to a suspension—a fate American Jenson Brooksby faced with an 18-month ban in 2023. Zverev called the process disruptive, particularly when testers arrive outside the designated hour, forcing players to alter plans. “It is an annoying process, I have to be to be honest, because we have to be at a certain place every single day where we kind of give our details of where we’re going to be for like an hour a day,” he explained. “But at the same time, if they show up not in the hour that we gave them, you still have to come back to the place.”
A personal story underscored his frustration. Recounting an incident from December 2024, Zverev described being summoned for a test while picking up his three-year-old daughter at Nice airport. “My slot was at 7 or 8 a.m., and they came at 9 p.m.,” he said. “I was like, I can’t, I am picking up a three-year-old child, and they were like, no, you have to come back, it doesn’t matter what happens.” The inflexibility, he argued, strips players of basic freedoms. “Just because you decided to show up at a random time and not the time slot that you’re given, doesn’t mean that I have to completely change my plans and leave everything,” he added, urging, “That system can be better and that system can change a little bit.”
On the court, Zverev is poised to capitalize on his Munich momentum, where he defeated Ben Shelton to claim his first title of 2025 on his 28th birthday. As Madrid’s top seed, with Sinner absent and Carlos Alcaraz withdrawing due to injury, he faces Roberto Bautista Agut in the second round after a bye. A two-time Madrid champion (2018, 2021), Zverev sees the tournament as a chance to close the gap on Sinner’s ranking points and solidify his Roland Garros seeding. Off the court, his call for a more considerate anti-doping system resonates with peers like Andrey Rublev and Ons Jabeur, who have also voiced concerns. As Zverev chases ATP Masters 1000 glory, his outspoken stance ensures the doping debate will echo beyond the clay, challenging tennis to find a fairer path forward.
