A bunch of the beat writers are saying "I wasn't surprised" that Nishioka was sent down, only by the timing. If that is true, I have to think the Twins have a viable plan B in place. One idea is that they are going to find a middle infielder outside the organization. But its hard to believe the Twins waited until Nishioka was sent out, if that was the plan B. Its possible they have been having talks with other teams and that the next shoe will drop soon.
Some people have suggested Brian Dozier would take the everyday shortstop spot with either Casilla or Carroll moving to the utility role. If that is a real possibility we will soon see those two trading positions on occasion.
Another possible scenario is that the Twins are willing to use Plouffe and Casilla as the backups at shortstop. That creates an opening for another bench player like Burroughs, Dinkelman or Hollimon.
Finally, there is what is probably the most likely scenario. Florimon or Chang are now competing for the utility spot. Florimon's skill at shortstop puts him a step ahead of Chang. But Chang has more experience.
Whatever happens, spring training has become a little more interesting.
