Buckeye's post is certainly an eye-opener. His struggles have been evident, but I didn't realize they had reached that extent. One caveat: like so many of the Reds, he's a streaky dude. He'll have his stretches of effectiveness.
In the meantime, his whole scenario makes me wonder whether he might be a candidate for conversion to a starter. One of his troubles out of the bullpen has been a tendency to drop off sharply with frequent usage. Maybe the every-fifth-day schedule would suit him better. He does seem to have an adequate mix of fastball, sinker, curve. And he definitely has the body of a starter. In the minors, he found success when they switched him from starting to relieving, but that seemed to coincide with his development of the two-seamer, or whatever it was that Tom Brown taught him. Given that he has made himself somewhat expendable as a reliever, it seems to be worth a shot.
