Several Q's here.
1) Does a half swing mean for the time being, it has been ruled a ball?
2) Does a checked swing technically mean it has finally been ruled a ball?
3) Does the offense ever have the opportunity to check on a half swing that's called a strike?
4) Depending on the answer to 3, is this consistent among all rule codes?
I would really like the rule refs, casebook refs, or umpire manual on 3/4 in FED if the offense can never appeal. Neither my son who plays HS nor I can find it.
Thank you all in advance.
