At first blush Grossman looked like a sort of poor man's John Cangelosi to me. Cangelosi's offensive skill set (switch hitter, good speed, very good on base skills) said 'center field', but his glove whispered 'not so fast'. Cangieman played all three OF positions, and while he wouldn't kill you with 15 days in center, he would cost a few runs over an extended period there. All in all, he was a pretty good 4th OF who played til he was 35, ancient for a career backup OF. But Grossman just doesn't have the glove or the speed you'd like to see in a 4th OF. At this point he profiles a bit like a utility middle infielder who is such a liability at short that he really should be the second option off the bench there. Back when teams used to squeak by with only 5 relievers and the bench was six deep even with a DH-only guy, you could afford to carry a niche player like that. With 12 pitchers, there's only one outfield-only reserve, and that guy better be able to play center. That brings me to my concern about Grossman for next year, which is that if he maintains his offensive output enough for the Twins to bring him back, it increases the likelihood that the Twins will bring back Dantana because of his ability to back up center. And while it's true that Rosario could play center if need be, I'm not sure that at this point he's a significantly better bet to pull his weight offensively than Danny S. Is there a Jim Edmonds School of Uncanny Fly Ball Reads we can send Kepler to in the offseason in case he needs to slide over to CF for a 10 games each year?
