Thomas Pannone tested positive for the anabolic steroid dehydrochlormethyltestosterone, or DHCMT. The suspension will start at the opening of the 2018 season.
The drug that Pannone tested positive for is the same drug that Chris Colabello was suspended for prior to the 2016 Blue Jays season. Much like Colabello, Pannone claims to not know how it got into his system.
Pannone recently released a statement via his Twitter account affirming his innocence. The young pitcher even explained a process he completed with Major League Baseball of undergoing a three-hour polygraph test under the administration of a former FBI agent.
