Jarred Cosart was "caught off guard" by the firestorm surrounding his alleged sports gambling activities and is cooperating fully with a Major League Baseball investigation.

The 24-year-old allegedly exchanged multiple direct messages with a gambling authority on his Twitter account at an undetermined time, and the interaction became public when it was shared on the social media site by a third party. Cosart deleted his official Twitter account after screen shots of the exchange began appearing on the Internet on Tuesday night.

Cosart spoke to reporters for about a minute at the Marlins' complex before heading to a back field at Roger Dean Stadium. Cosart and Michael Hill, the Marlins' president of baseball operations, both said they have been given no timetable for a conclusion to MLB's investigation.
