not to nitpick, but Wells has been horrendously bad both this year and last year.
UZR puts him at -14.3 last year and -20.2 this year.
The fielding bible put him at -7 runs last year and had this to say
If I could see his +/- this year, I'm guessing it would agree with UZR that he is absolutely terrible in the OF. I think we're seeing another Andruw Jones.
