The Major League Baseball Players Association had no knowledge of Jenrry Mejia's dissatisfaction with his representation until comments from the New York Mets reliever were published in The New York Times, according to Tony Clark.

Mejia received a lifetime ban last month after testing positive on three separate occasions for performance-enhancing drugs.

In the report published in the Times, Mejia claimed he was only guilty of the first offense, and that he was being railroaded by Major League Baseball officials.

"Anytime there's a concern from a player about a situation related to the support he feels he got or didn't get, it's concerning," Clark said. "But, again, we are confident that we take every case seriously and provide the support from start to finish for players. Being a player, you can trust that is the case."

Although he is banned from baseball, Mejia has the right to reapply for reinstatement for the 2018 season.
