Yeah, his jump in offensive production last year seems a little excessive. Still, he's a solid trade chip for the White Sox now, unless they plan on keeping him around as Yasmani's backup. Put it this way, if they DH Grandal a fair bit, it will keep the wear and tear down, and they get a good C for four years. Except that McCann is looking at a pretty nice raise through arbitration this year. The White Sox may have more money to play with than the Brewers, but it doesn't grow on trees for them, either. Also, Grandal's bat is great at catcher. It's average at best as a DH, though.
