Rarely do 10U's. Will only do them on timed games.
Got caught yesterday when one of the blues scheduled for the
championship game had to leave. (My bad, cause I had just
finished doing 14U championship and should have been in my
car on the way home instead of chatting with an old friend
about this and that.) I was still dressed for plate, and it
was the plate umpire that had left.
I agreed to do the game.
After a couple of innings and lots of high and low pitches,
of which I am calling balls, one of the coaches from the home team
comes over and says, "Blue, you have to expand the strike
zone in 10U. The rule is to go higher and lower.
If you don't, we will be here all day."
DUH.
Game is 1:05 finish.
May be wrong, but I do not alter my zone for 10U when I do have to
call that age. Main reason most coaches that know me, don't
want me on 10U's.
