Byrd was 4-2 last season with a 4.7 ERA. It's better then what they are currently getting. I agree I would also like to see Bowden/Tazawa getting the starts. But remember these guys are on innings limits. They might be a September call up, but they also might be coming out of the BP. He's going to need 4+ starts to be ready anyways. So he won't be joining the team until right before/at the September roster expansion. Considering that. He's not that bad of a September call up. If Buchholz could go 4-2 with a 4.7 ERA, people would be celebrating.
It's really not that big of a deal anyways.
