New York Mets reliever Jenrry Mejia has received a permanent ban for a third performance-enhancing substance violation, the MLB announced on Friday.
Mejia, a 26-year-old right-hander, was suspended for 80 games in April 2015 for testing positive for Stanozolol.
He returned and pitched in seven games before being hit with a 162-game suspension in July for testing positive again for Stanozolol and Boldenone.
The latest suspension is also for Boldenone. He can apply for reinstatement in one year, but is required to sit out at least two years before being allowed back into the game.
Mejia, the first MLB player to receive a permanent ban for drug violations, enjoyed his best season in 2014 when he recorded 28 saves with an 3.65 ERA.
He has a 9-14 career record, 162 strikeouts and a 3.65 career ERA to go along with those 28 career saves.
A statement from the Mets read: "We were deeply disappointed to hear that Jenrry has again violated Major League Baseball's joint drug prevention and treatment program.
"We fully support MLB's policy toward eliminating performance-enhancing substances from the sport. As per the joint drug program, we will have no further comment on this suspension."
