I guess I don't understand the last sentence. Shouldn't the goal to use as many workable innings at the majors instead of the minors? Pitchers seem to leave the game due to physical deterioration much quicker than batters. Also, pitchers are the causation to the batters reaction, it is the batter that needs to adjust to the pitcher, not the other way around. Because of those two things, it is the pitchers that I'd call up early and let the batters season in the minors if needed. I understand this is the opposite approach the Twins appear to take. On a more fundamental note, relief pitchers who throw 100 MPH don't tend to last long. Even if he is lights out for a few years, there's a very good chance he'll never get a shot at a true career-making free agent contract. Let him get his service time and give him a better chance of making his money. Also, it's a lost season, he has options and he's already on the 40-man, what's the harm?
