I imagine it's gonna play out like this:
Made at 3B, Pratt at SS, Burke at 1B, and Fischer at DH.
Turang holds down the fort at 2B for the next couple years until Pena is ready for the major leagues. Then we trade Turang for what is hopefully a decent haul and put Pena at 2B. As for Luke Adams, I imagine he is traded at some point in the near future. He is a fine prospect but is quickly becoming overshadowed by both Fischer and Burke.
