TODAY: Cosart briefly addressed the situation today, telling reporters that he was simply following MLB’s protocol, per MLB.com’s Joe Frisaro (Twitter links). Cosart also said that he was not behind the creation of a new Twitter account, attributed to him, which had figured into some reports on the matter.
To be clear, all that is known at present is that the league is exploring the matter. The league is quick to pursue information regarding any gambling-related issues, and its involvement should not be read to imply any wrongdoing, or even suspicion thereof.
As Elfrink explains, a Twitter user has posted screenshots of purported Direct Messages sent from Cosart’s Twitter account regarding an unspecified betting matter. Cosart’s Twitter account has since been deleted. It is not even yet apparent whether there is any credible suggestion that Cosart has engaged in any gambling-related activities, let alone actions involving the game of baseball in any way.
Given the highly uncertain underlying issue here, and the fact that it is not even clear whether MLB intends to conduct a full investigation, it is far too soon even to speculate whether there are any possible grounds for future discipline. For sake of reference, MLB Rule 21(d) prohibits players from “bet[ting] any sum whatsoever upon any baseball game,” providing a one-year ban if such activities occur with regard to a game in which “the better has no duty to perform” and a lifetime ban in which the bettor does.
