Svrluga on MLB Network, and the talking heads on WJFK are all saying that Rizzo is deeply embarrassed by what went down with Black and Baker, and that the decision to only offer a one year deal to Black wasn't Rizzo's. They are saying that there's a lot of tension between Rizzo and the Lerners dating back to Rizzo not being able to add salary at the 2014 trade deadline, in addition to 2015, and the Scherzer deal that was largely between Mark Lerner and Scott Boras. They are speculating that after the Williams hire, management wanted more involvement in this year's manager hiring decision.
Rizzo's deal expires at the end of this year. It seems like a good bet that he's gone after then, if not sooner.
