I could see them holding on to a couple of these MiLB contract guys for an extra week or two by creatively managing the roster to drag out their having to make 40 man roster moves. The wild card is always what kind of opt out date that guys who signed MiLB deals, but may not be worth cutting someone else to keep around. If that date is after opening day, maybe they get sent to Charlotte for a week/month so that they can kick that can down the road to see about injuries etc.
