That's my guess. I can't imagine a guy who has never had any patience at all just magically deciding to start taking pitches once he hits the big leagues all by himself. It kinda makes sense but can that really affect someone's patience? I mean can pitchers really figure out how to trick him into being less patient at a far greater clip than they do now?
What's the deal with Colvin? He's seemed super patient as of late. I'd assume that isn't really a product of pitchers not figuring him out yet, but I could be wrong. Is it possible Jarimillo had that big of an influence already>
