MLB could discipline the Cardinals, possibly with a fine or a loss of draft picks, but has said only that it looked forward to getting details on the case from federal authorities.
"Now that the criminal process has been completed, Commissioner [Rob] Manfred has asked the Department of Investigations to conduct a complete investigation of the facts in this matter, including requesting information from the appropriate law enforcement authorities," the league said. "The commissioner hopes that the investigation can be completed promptly to put him in a position to take appropriate action."
I think what happened was the Astros complained about the hack and the FBI stepped in before MLB did any real investigation. The hacks occured during the draft and at the trade deadline.
I think they should lose a few draft picks next season.
