Good umpiring in HS games is not hard to find. Good CONSISTENT umpiring is, alas, often hard to find. I tip my hat to those who work hard to make baseball games possible in the first place.
I will add that my son, a 2017 catcher who can get very frustrated when he gets a late-game called strike that he, having been catching all along and having both the best view of the pitches and "working knowledge" of the umpire's strike zone, was not a strike until then. So being a catcher can be a double-edged sword.
Some general observations about HS umpiring (1) the SZ for "pretty" curveballs often expands as the game goes on, (2) low and away strikes seem to be the most difficult to call consistently, and (3) "situational" SZ's can still appear for teams with clearly struggling pitchers and teams with many kids who are obviously looking for the walk.
