"Penalties for players who place non-baseball bets with illegal bookmakers fall under the discretion of the commissioner; the last case was in 2015, when then-Miami Marlins pitcher Jarred Cosart was fined an undisclosed amount."

If he's only guilty of sending money to an illegal gambling operation to pay off his interpreter's debt, I can't imagine MLB would do anything more than a fine. If he's in prison, which I think is highly unlikely, the decision will have been made for them.
