Toronto Blue Jays first baseman Chris Colabello has been suspended for 80 games by MLB after testing positive for a performance-enhancing substance.
Colabello tested positive for dehydrochlormethyltestosterone, which boosts strength and speed.
An MLB statement read: "Blue Jays first baseman Chris Colabello was suspended for 80 games without pay on Friday for violating Major League Baseball's Joint Drug Prevention and Treatment Program.
"Colabello tested positive for dehydrochlormethyltestosterone, a performance-enhancing substance."
Colabello responded to the ban with a statement via the MLB Players' Association, in which the 32-year-old stated that he is unsure how the substance was found in his urine.
"On March 13, I got one of the scariest and most definitely the least expected phone calls of my entire life," the statement read.
"I was informed by the Players' Association that a banned substance was found in my urine. I have spent every waking moment since that day trying to find an answer as to why or how?
"The only thing I know is that I would never compromise the integrity of the game of baseball. I love this game too much! I care too deeply about it.
"I am saddened more for the impact this will have on my team-mates, the organisation and the fans of the Toronto Blue Jays.
"I hope that before anyone passes judgement on me they can take a look at the man that I am, and everything that I have done to get to where I am in my career"
Colabello is batting just .069 with zero home runs and one RBI this season, but he had a terrific .321/.367/.520 slash line with 15 home runs and 54 RBIs in 101 games last season.
