Rogers has two pitches, with an extreme platoon split. They needed a LH RP last year, and didn't call him up at all. It would not have stopped him from going back to starting this year if it was the right choice. May has 4 pitches, and was succeeding as a starter when they moved him. Those two are NOT like each other at all. Finally, at some point, it is more valuable to actually use a guy in the majors, than it is to wait forever for him to be something in the minors. IMO, Rogers should have been up , in a playoff race, when the Twins needed help. Instead, they didn't get 1 penny of value from him last year.
