No he's not. I'm sure MLB has contract with certain companies for sponsorships that are allowed to be shown on TV, and they have agreements to respect those partnerships. It's clear by that letter that Bauer violated something that he agreed to, and it's probably not a great idea to put your own team in a bad light like that. Especially one that just paid you an enormous amount of money. I guarantee you whatever deals he has, none is more lucrative than the one he has with the dodgers. He should honor that one above all the others.
