I seriously belive that the final ship of the Chapman-to-the-rotationflotilla sailed this past spring - not tht that is bad thing - I doubt Arolis would be omre than a pedestrian starter after taking into account the loss of velocity he would see after converting to a starting role.
I also think that at least two, if not three of Latos, Cueto, Bailey and Leake will still be in the Cincy rotation come 2016 along with Cingrani and Stephenson. I aso believe somone like Moscot (among others) may push for an open spot if there is one.
