Sorry. Maybe I'm not being clear. This didn't happen in my game as I was merely asked my opinion about the legality of such action. Let me try this one more time.
Prior to the game. Team A, including the pitcher and catcher, takes the field for infield/outfield practice, infield/outfield warmups, fungoes, etc. While the coach is hitting infield/outfield practice (or fungoes, if you prefer), Team A's pitcher is throwing pitches to her (Team A's) catcher while on the field from the actual (game) circle from the actual (game) pitcher's plate to the catcher positioned behind the actual (game) home plate. Neither the pitcher or catcher (both from Team A) are involved in the fungoes being hit by the coach of Team A. Neither the pitcher or the catcher (again, both of Team A) are involved in any of the throws that are being made by their Team A teammates during the infield practice. The Team A pitcher is simply using the actual field has her bullpen while her Team A teammates take infield practice.
I offered my opinion there was no prohibition against this. The state association has since responded to this umpire's association directly deeming this a safety issue and for umpires not to allow this.
I was just curious what the fine folks on this board thought. (Apparently they think I can't explain a situation very thoroughly.)
