Sorry, I forgot, Defense is judged by errors and fielding %. I'm sure that's what Bert and Dick are using. SO yeah, Tigers Are WAAAAAAY better on defense :-)
Announcers just got done saying Tigers defense was way better than the Twins this year. That didn't sound right so I checked. Twins 29th in DRS. Tigers 28th.
I know for sure that when I see the lineup and Mauer isn't in it, I find it easier to not watch it and go do something else. And my favorite current player is Kepler.
Grossman has 13 DRS, but he's played 500 Inning in the OF. Santana has -10 DRS in the OF this year in only 440 innings played in the OF. Yeah, perhaps he's better than Grossman, but then you have to factor in he can't hit or steal bases.
