Although it will never happen in HS Baseball, this is all evidence that we need an electronic strike zone.
Too often, the game depends upon what pitcher goes and with his style of pitching and how it matches up with an ump and "his" strike zone. A sinker ball pitcher or a pitcher with a curve that drops off the end of the table is in bad shape should he happen to pitch on a day where the ump doesn't call the low strike. Or it can be any number of ways that one pitcher gains an advantage over the other depending on the ump's strike zone.
Don't tell me that as long as he is consistent, it is fair. It (the ump's particular zone) not only gives one pitcher over another if their stuff matches up better with the ump, but it can help a team that can't hit stay in a game with a team that can. An ump can take the hitting out of the game by the strike zone he calls. Or vice-versa.
Hopefully that an ump is doing the best he can goes without saying, but I do fault the ump who tries to put "his stamp" on the game. Any ump that says anything about "his" strike zone is missing what the job is.
