During the 2025 Cincinnati Open, American star Amanda Anisimova faced Philippine sensation Alex Eala in a high-stakes third-set thriller. The match was already tense, with Anisimova leading 6-4, 5-6. In the final games, as Eala fought back with powerful groundstrokes, Anisimova quietly reached for a plain, unbranded plastic cup on the courtside table. Live on Tennis Channel, commentators froze mid-sentence when they noticed something unusual: the drink was a foamy, amber-colored liquid swirling inside.

Within seconds, social media exploded. “What is that?!” “Is she doping?!” “Tennis world in chaos!” Hashtags #MysteryDrink and #AnisimovaScandal trended worldwide, with fans and insiders speculating everything from energy drinks to illegal supplements. The mystery deepened when a leaked toxicology report surfaced on a private tennis forum. According to the document, obtained by a senior reporter, the beverage contained a banned substance — a selective androgen receptor modulator (SARM) not listed on the International Tennis Federation (ITF) or World Anti-Doping Agency (WADA) prohibited list at the time of testing.

Sources close to the player claimed the drink was secretly handed to Anisimova by a trusted team member during a routine hydration break. The substance, reportedly a new synthetic compound, was designed to enhance endurance and recovery while evading standard urine tests. Anisimova has always been a clean athlete, known for her athleticism and dedication to training, but this incident raised serious questions about the safety and regulation of on-court supplements.

The moment the report circulated, the tennis community was thrown into turmoil. WTA officials confirmed they are now investigating the source of the drink. Anisimova’s camp released a brief statement: “Amanda is 100% committed to clean sport. Any allegations of wrongdoing will be fully investigated and refuted.” No official doping violation was confirmed, but the incident has cast a shadow over her title hopes.

As the story unfolds, fans are divided. Some demand stricter oversight of on-site beverages, while others point to the growing complexity of banned substances in modern sport. One thing is certain: the mystery drink scandal has turned an otherwise ordinary WTA match into the biggest talking point of the season.
