Who cares about this year? He won't be tremendous next year, or in 2011, when the Reds should be thinking about contending. Not this year, when they are 10 games back.
You just traded for a 34 year old 3b who can't stay healthy and has 8 HRs this year. He's had 27 total since 2007.
This makes no sense, unless they really just wanted to unload Encarnacion because he was hitting atrociously.
