To me, the question of moving to Santana to shortstop opens up the question of "What do you do with Escobar?" He's older, and not as sexy of a long-term prospect as Santana. But he's having a good season and his power spike and solid-to-good defense at short gives him value, something the Twins have rarely had at the position. I don't have any qualms about leaving Santana in centerfield for that reason, to see what he can do long-term against major league pitching.
