An investigation by MLB revealed no evidence that Miami Marlins pitcher Jarred Cosart has bet on baseball.

An investigation by MLB revealed no evidence that Miami Marlins pitcher Jarred Cosart has bet on baseball, the league announced on Friday. 

MLB investigated Cosart for possible involvement in sports-related gambling after a screenshot of direct messages that were allegedly from Cosart looking for gambling advice was shared by a third party on Twitter. 

Cosart was fined an undisclosed amount by the league for violating a rule that prohibits players from placing bets with illegal book makers or agents for illegal book makers. The rule applies to all sports and events.

MLB prohibits its employees from gambling on baseball, and rules state betting on a game that does not involve a player's team results in a one-year suspension. Betting on or against a player's own team results in a lifetime ban, such as the one Pete Rose received in 1989.

Cosart recently told the Miami Herald that he has never bet on baseball and never will. He said he was cooperating with the investigation, something the league also said in its statement on Friday.
