Doping suspensions in tennis continue to make headlines, with notable cases involving top names like Jannik Sinner and Iga Świątek. Former British No. 1 Tara Moore, who was previously cleared of an anti-doping violation, has now received a four-year ban after the Court of Arbitration for Sport (CAS) upheld an appeal by the International Tennis Integrity Agency (ITIA).
As Moore makes headlines once again, here’s what to know about the British tennis player.
All About the Former British Doubles No. 1 Tara Moore Amid Her Four-Year Doping Ban
Moore, a Hong Kong-born British tennis player, developed a passion for the sport at seven and later trained at Florida’s Nick Bollettieri Tennis Academy before becoming a professional. She achieved career-high WTA rankings of No. 145 in singles and No. 77 in doubles, though she is yet to claim a title in either discipline. The 32-year-old is currently ranked No. 187 in the world in doubles and No. 864 in singles, placing her 11th and 27th among British players, respectively.
A highlight of her career came in February 2022, when she became the British No. 1 in women’s doubles for the first time. However, that achievement came nearly four months before she was handed a provisional suspension after testing positive for the banned anabolic steroids nandrolone and boldenone in a blood sample.
Moore maintained that she had never knowingly consumed a banned substance in her career, which the independent tribunal ultimately agreed with following their investigation. They concluded that the Brit had ingested contaminated meat, which led to the presence of the substances in her system in the days leading up to the test.
The 32-year-old remained provisionally suspended until December 2023, when the panel cleared her of any anti-doping rule violation.
ITIA’s Official Issued a Statement After Tara Moore Was Handed a Four-Year Doping Ban
While the case initially seemed settled in Moore’s favor, the International Tennis Integrity Agency (ITIA) remained skeptical of her explanation. It later appealed to the Court of Arbitration for Sport (CAS), citing the high levels of nandrolone found in her sample, and the CAS recently ruled in favor of the appeal. ITIA’s Chief Executive Officer, Karen Moorhouse, issued a statement in the wake of the verdict.
The Court of Arbitration for Sport (CAS) has today upheld an ITIA appeal in the case of British tennis player Tara Moore, issuing a four-year period of ineligibility.

“For the ITIA, every case is considered according to the individual facts and circumstances. Our bar for appealing a first instance decision is high, and the decision is not taken lightly. In this case, our independent scientific advice was that the player did not adequately explain the high level of nandrolone present in their sample. Today’s ruling is consistent with this position,” he said.
It is worth noting that Moore filed a cross-appeal with CAS, seeking to dismiss the ITIA’s appeal. However, CAS rejected Moore’s appeal and confirmed that her four-year period of ineligibility would begin on Tuesday.
