In a press conference held on Wednesday afternoon, Red Sox chairman Tom Werner said former manager Alex Cora admitted he "played a central role in what happened in Houston".
I assume Cora's possible involvement in illegal hijinks regarding the 2018 Red Sox was also a topic of conversation at that meeting, but nothing was said about that.
Kennedy did tell everyone that the jettisoning of Cora was "exclusively" related to the results of the Astros investigation and unrelated to the ongoing investigation of the Red Sox. (Which is probably not true, but MLB is still investigating the Red Sox, so that's what he has to say.
