Anthony Bosch is expected to ask a judge to reduce his sentence based on his cooperation with the government and with the MLB.

CBS4 obtained a copy of a letter an attorney for the MLB sent to U.S. District Attorney Wifredo Ferrer, saying in part:

“MLB vigorously maintains that Anthony Bosch has not only provided invaluable assistance to it in enabling the successful suspensions of fourteen players, but also has assisted in sending an important message to the millions of young athletes who emulate their heroes and therefore feel pressure to use pes in pursuit of their athletic dreams.”

Bosch plead guilty in October for his role at a former Coral Gables clinic which reportedly sold banned steroids to MLB players, including Alex Rodriguez.

That was after Bosch’s bail was revoked for testing positive for cocaine twice.

Bosch and six other people who allegedly made up his supply and distribution network were indicted in the MLB doping scandal investigation.
