If he ends up doing well, it's a good "problem" to have. I'd hold some money in reserve for the summer, and give Arroyo, Munoz, Chavis, Arauz and Chatham a shot at proving they can be a net plus at 2B. If not, and we're in the race, then we trade for a 2Bman.
Or, we sign a 2B/4th OF/CF type player for not too much dough.
