Moniak is progressing much faster than Williams, who tore up A ball in a hitter's league but never showed any progress in developing plate discipline. Moniak has made huge strides from a free swinger to a disciplined hitter this year.
Progress is always more important than snapshot performance for prospects.
Does Listi's slow start at Reading outweigh his torrid pace in AAA ball? Now we'll have to see if he maintains it, but if he does, you can pretty much throw out his first couple months - adjusting to higher levels is the key metric for prospects, a 1.000 OPS in A ball isn't worth nearly as much as an .850 OPS in AAA.
The one joker in the deck is that AAA uses the ML baseball, while lower levels use an easier to grip ball, so the transition for pitchers from AA to AAA has become more difficult, at least initially. But has overall production by hitters in AAA ball increased this year, or is this just a transitory effect on pitchers when they're promoted?
