Seems as we move up the baseball food chain that umps call fewer and fewer balks in our area.
In little kids' ball, they occurred all the time. Umps would scream out "BALK!" at the top of their lungs (scaring the heck out of the 12 year old pitcher a few feet away). A memorable and embarrassing lesson, no doubt
Later, I saw one JV Legion pitcher get hit three times in two innings with balks.
But in HS varsity I see almost none called. True, the pitchers are smarter by then. But is there a difference in ump thinking in regard to balks at HS varsity level?
How often are pitchers hit with balk calls in your area?
