Drew Pomeranz's turnaround this season came with the development of a plus cutter. He isn't just having a lucky season, he's a young pitcher who found himself.
27 year old arm, three years of control, decent groundball numbers. Maybe this doesn't turn into a complete disaster?
Considering that this team hasn't developed any elite pitchers in a long time, it seems like a massive overpay to trade away an ace-potential prospect for someone with such a short track record.
My grade: C-
