From a substantive matter, I guess I mostly agree with Cashman. It’s certainly true that the Yankees didn’t really have Joba “bounce around” from the rotation to the bullpen, anymore than any starter who breaks into the big leagues in the bullpen is bounced around, and that has been a common practice in MLB for decades now. To that end, it’s also extremely stupid to say that that cause Joba to need Tommy John surgery in 2011, both because there’s no evidence for that at all and because, by that point, Joba hadn’t pitched out of the rotation since September of 2009. And the point about other teams is certainly true, though I’d politely suggest Cashman take that up with the local media that he happily enables most of the time.
On the other hand, it’s sort of hard to get past the fact that Cashman pulled the plug on Joba as a starter after just one full season in 2009, ostensibly because Joba’s stuff played better in the bullpen (something that Cashman has said publicly). So really, what the heck does he expect the people who thought Joba should be a reliever from day one to think when he’s basically signaled, at least, that they were right all along? Perhaps if he hadn’t been so quick to give up on Joba’s development he wouldn’t have to deal with all of that criticism that he “stews” in these days.
