In Little League, and all other rules codes, I know that the pitcher is excepted from a batted ball having gone by an infielder for the purposes of the runners interference with a batted ball rule. My issue is that I can’t find anything that explicitly states that. Is there an official interpretation book for Little League that says the pitcher is excepted? Or is there a rule that actually says the pitcher is excepted and I am just not finding it? Thank you in advance!
