The opener/bullpen game works if you have the luxury, as the Twins do, to comeback with a pitcher or two who can throw three or four innings. (Actually, I would use the opener in the case of Hill and especially Odorizzi for the remainder of the season). You are carrying an abundance of pitchers. But, yes, with the double-header allowing you to spotlight a 40-man guy - let us see Chalmers and Duran if at all possible. At worst, they face only three batters. At best, they shine beyond expectations, and will cause hard decisions to be made on pitchers like Poppen and Smeltzer.
So, what are the chances the Twins let Trevor May walk?
Anyone believe Fernando Romero still has a future with the Twins?
