Average At Worst

AITOOW thinks strategy/foreknowledge can't be very important to hitting a baseball? If it was, pitchers and catchers would have the edge. They are the positions that contemplate pitch selection in the greatest part. They should be best able to "diagnose" and defeat the opposition's approach. Yet, they mostly maintain the worst batting averages. Pitchers may have the excuse that they don't practice hitting as much as other players. Some cite fatigue as a factor for catchers. Maybe they both overthink it.
