Former Red Sox infielder Danny Santana was suspended 80 games by MLB after testing positive for PEDs.
Santana was one of three players suspended, per the Athletic’s Britt Ghiroli. The others –infielder José Rondón and pitcher Richard Rodríguez — were both free agents as well.
Per Ghiroli, all three players tested positive for Boldenone — a synthetic derivative of testosterone that was originally developed to rehabilitate injured horses. Like most anabolic steroids, it has a long (and unpleasant) list of adverse effects when used by humans, but numerous athletes in a variety of sports have tested positive for it.
