The AA bum (JC Sulbaran) is the better prospect, #5 Reds prospect preseason, but probably the 5th best SP in the system at this point behind Stephenson, Cingrani, Lotzkar & Corcino.
Donnie Joseph has great numbers this year, but as a rule I never care about trading minor league relievers (see: Boxberger, Brad).
I don't like Broxton. Walks the ballpark, declining K rate, fake ERA this season. My fear was that the Reds gave up one of the "big four" SP's, which i'm ok with trading, but not for a guy like Broxton. When I saw that it was Sulbaran & Joesph, I was relieved. Meh trade, hopefully he pitches well and doesn't see a ton of really high leverage situations because I don't trust him, but we gave up next to nothing.
