The International Tennis Federation is still swimming with the guppies as far as catching drug cheats.
An appeal to the Court of Arbitration for Sport upheld a two-year suspension assessed to unknown 17-year-old Kazakh player Arsan Arashov, who tested positive for meldonium in June 2016.
Last week, the ITF imposed a provisional suspension on American Spencer Furman, who tested positive for D-amphetamine at the Challenger in Cary, NC in September.
It was the only pro match Furman, 20, had played all season.
He’s a sophomore at Duke University, and has no ranking.
