I would trade him. Realistically, after last year, it would not be suprising if he had similar numbers next season. Trade him away while he has some value, and sign a sure handed SS who has great range an a glove. Help the D, and bat that guy 9th. With the lineup the Tigers have, they can afford to have a guy who will bat slightly less than Peralta did with no power. Ill take the extra defensive help and a slightly weaker bat.
