I'm on the same page. Let Colson sustain some success in AAA until after the ASB or trade deadline at least. Bring him up once you're confident he's injury-free and producing in a way that he can sustain in MLB.
I don't know why Baldwin isn't up yet, especially over Capra. All I can think of is they think Baldwin is in the Elko camp of AAAA players, but even that's better than Capra.
