Three concerns with the Wes Johnson hire. Usually major league pitchers are in need of minor refinements rather than major overhauls or a build up from little established fundamentals like a raw prospect or a college kid. Major league pitchers are in such different places in their career from where college kids are,that it requires a a very real mind shift to deal with them. The 2nd concern is is managing work loads, when to get up relievers, when to let starters work through early inning difficulties and other things of this nature. Molitor and his pitching coaches seemed to struggle in these areas at times, and he and they had been around major league pitchers for years. The final concern is the mental aspect of pitching in the majors. All major league have enough stuff to get people out, the best ones or at least the ones with the longest careers, have to figure out the art of pitching. Using one pitch to set up another, handling failure and the other mental aspects of pitching. While some of that is certainly addressed in college, one would think that this part of the game is on a different level in the majors.
