I have been umpiring high school and youth baseball for about 10-years. Over the past few years the quality of youth baseball (not high school) but rec ball has gotten to the point where I won't umpire (Babe Ruth, Colt, etc) games because the quality of ball is so bad that the frequency of getting hit is too great a risk.
With the number of travel, tournament and similar programs the kids left playing the traditional community based programs is so thin in talent that umpiring there games has become too risky. I did a game last week for a 15/16 year old program where I am doubtful that any player had played HS ball. Being behind the plate I was constantly doing everything I could to avoid being hit. The pitchers couldn't pitch and the catchers couldn't catch. In one game I was hit in the arm and wrist twice, once in the stomach and once in the private zone.
I was using the standard slot position; however, it is tough when a catcher sets up with a 2-0 count on the outside and you go with him, then the pitcher goes inside and you end up taking a foul ball to the mid-section. Or you have a kid that wants to tryout his new slider which he has mastered to 58 feet and you have a catcher that has not been either taught or mastered blocking a ball in the dirt and you get hit.
It is no longer safe to umpire local youth games. I have scratched all games involving programs where players do not have at least a solid year of playing high school baseball.
My safety is more important to me now than being part of what I consider a dying part of the game; youth baseball.
