Not too shabby a pick up for me. Not much for RBIs (mostly, RBI opps are situational anyway... simply means the guys batting before him aren't getting on base) but if you need a pure slugger who has (so far) been hitting for avg., too and not punching out a lot, you've got a solid commodity... Adam Dunn without all the K's and a much better BA.
The big question is how long will he keep this up? Impossible to say, as there isn't a lot of history behind him but he does have power.
I think being w/ detroit, though, a lot of people are waiting for the other shoe to drop and the Tigers to tank. I think they have too much talent this year for a complete collapse on both sides of the ball.
