I have some muddled thoughts on the minors -- such as, seeing as how the AA pitchers so far are dominating. That's not surprising, but it's an example of AA pitchers facing AA hitters. I realize these guys need time to walk before they can run, but I am also of the belief that the best AA pitchers ought to be pitching against AAA hitters. I don't care if they win and I don't buy into the "mental" issues that come with getting bonked out of a game.
Abbott can throw a half-dozen low-hit, high-K games against AA hitters and prove he belongs in a higher classification. Or you could just put him there and he has a level of experience that gets him to GABP a year sooner.
As for hitters, that same logic does not apply. Those guys would not benefit by moving up the same way pitchers would.
Catchers also need to learn slowly. The leap from amateur to pro ball for a catcher is exceedingly steeper.
