I'm sure you didn't mean it, but this example is a tad misleading. Carlton Fisk was a top draft pick, then played high A ball at age 20 and destroyed the Midwest league's pitchers (1000+ OPS). It's true that he stagnated at Double-A at ages 21 and 22. But he at least was getting on base okay for a catcher (.321 and .333 OBP). Bill Hall, who also played Double AA at 21 had a .279 ON-BASE percentage.
The Brewers being the Brewers promoted him to the majors the very next year.
So the only major similarity I see between the two players is that they were both rushed to the majors before dominating either Triple-A or Double-A. But while Fisk was non-dominant, Hall flat-out sucked.
Generally speaking, guys who have zero prospect pedigree (Hall was a 6th round pick) and NEVER dominated in the minors (not only did Hall not dominate, but he only had a portion of one season where he was above-average), do not overnight figure out how to hit.
Bill Hall is a hacker, who developed a little more power last year. Pitchers will learn (some have already learned) to keep the ball off the fat part of the plate, and he'll get himself out most of the time.
