SEATTLE — Seattle Mariners infielder Tim Beckham has been suspended 80 games as part of baseball’s joint drug agreement after testing positive for stanozolol, a banned performance enhancer, Major League Baseball announced Tuesday.

Beckham’s suspension is effective immediately and ends his season.

In a statement released through the players’ association, Beckham says he took a product from a “trusted source, who had advised it was safe to take. Regrettably, the product was tainted.”
