So two weeks ago I was behind the plate for a 14U semi-final. The field had a strange grading where the area behind home plate sloped downward. So, the batter was at plate level, the catcher was a few inches below him and the umpire was below the catcher. I was probably a good 12 inches lower than the batter. I tried to get my eye level to the letters of the batter like I always do, but I was fully standing to do this on a few of the taller hitters (one kid was massive, maybe a 6' 3" 14 year old and standing (I'm about 5'11") I was a little below the letters). Needless to say I was extremely uncomfortable fully standing behind the plate. So, after the first inning, I touch a normal crouch in the slot. I felt more comfortable, but now pitches that appeared to be belt high were actually knee high and pitches that were knee high were an inch off the ground. As a result my zone was very low. I was consistent with it for the game but I knew that I called some low strikes that were probably unhittable.
So the last two weekends I've done games and I've been overthinking my zone. We all miss two or three close calls a game, but I'm missing more like 3 or 4 an inning right now. I can't get out of my own head and with the championships for the spring league coming up this weekend I don't want to be a factor in the title games. Does anyone have any advice to regain my confidence?
