Facundo Bagnis Suspended for Doping at US Open: Implications for Argentine Tennis

Tennis Star Facundo Bagnis Faces Doping Suspension After US Open Test

new York, NY – October 24, 2025 – Argentine tennis player Facundo Bagnis has been provisionally suspended from all competition after testing positive for a prohibited substance during the recent US Open tournament. The International Tennis Integrity Agency (ITIA) announced the suspension, which Bagnis has voluntarily accepted, on Thursday.

The Allegation and Initial Response

The 35-year-old Bagnis, who achieved a career-high ranking of 55th in November 2016, was notified of the potential anti-doping rule violation on October 2nd. The issue stems from a sample collected on August 18th, during the qualification rounds of the US Open, where he suffered a first-round defeat to Australia’s James Duckworth. Analysis of the sample revealed the presence of hydrochlorothiazide, a diuretic and masking agent prohibited under the Tennis Anti-Doping Program for the 2025 season.

According to the ITIA, hydrochlorothiazide requires a valid permit for use, which Bagnis did not possess. Despite this, the player opted to accept a voluntary provisional suspension on October 18th, with any time served to be credited against a potential future sanction.

Impact of the Suspension

The provisional suspension immediately bars Bagnis from all tennis activities, including playing, coaching, and attending sanctioned events organized by the ATP, ITF, WTA, Tennis Australia, the Fédération Française de Tennis, wimbledon, the USTA, and national associations. This represents a meaningful setback for the veteran player, who has claimed 17 Challenger titles and reached two ATP finals throughout his career.

Bagnis’s Statement and Defense

Following the ITIA’s announcement,Bagnis released a statement expressing his shock and dismay. He described the situation as “one of the worst moments” of his professional career and affirmed his complete cooperation with the ITIA investigation. The player maintained his innocence, stating, “I would never knowingly take something prohibited,” and expressed confidence that the truth would ultimately prevail. Bagnis’s team suspects potential cross-contamination as a possible description for the positive test and stated they are working towards determining the cause.
