The 2015 Major League Baseball regular season hasn’t even started and yet, it’s already getting headlines for reasons that new Commissioner Rob Manfred probably doesn’t want to deal with this early in his tenure.

According to multiple reports, Miami Marlins starting pitcher Jarred Cosart is under investigation by the commissioner’s office over his alleged sports-related gambling ties.

MLB spokesman Pat Courtney confirmed to the Miami New Times that Manfred’s office is currently investigating the matter, which centers around multiple Twitter exchanges between the 24-year old Cosart and a person who is being described as a so-called “gambling expert.”

The tweets became public when said “gambling expert,” identified as @ghostfadekillah, posted screenshots of the DM exchange between him and Cosart, showing the latter sending DMs referencing that he had “bet LARGE” on something and “hammered” an under play.
