Miami Marlins pitcher Paul Campbell has received an 80-game suspension from Major League Baseball on Monday for violating its performance-enhancing drug policy.  

The 25-year-old Campbell made his major league debut April 3; he tested positive for dehydrochlormethyltestosterone (DHCMT), according to MLB, and will be suspended without pay. Campbell, through the MLB Players’ Association, released a statement noting that he tested positive for “10 trillionths of a gram” of DHCMT, an amount he says has “no performance-enhancing benefits. I have unfortunately become one of many athletes, across multiple sports, who are presenting themselves to the world and asking for members of the anti-doping world to help us find answers as to why this metabolite is continuing to show up in athletes’ bodies and ultimately costing them significant detours in their careers.”

Campbell, a 21st-round pick out of Clemson in 2017, posted an 8.74 ERA in five appearances with Miami this year. He started and lost against the Nationals on Saturday, giving up four earned runs in 3 ⅔ innings.
