ASA unreported sub

[shipwreck]

In ASA the rule says that an unreported sub can be appealed while the player is in the game. We had this situation last night. In the third inning the visiting team brings to my attenion ( I am PU ) that a girl from other team hadn't reported in the other half of the inning. She had batted but they didn't bring it to my attention then but later. My question is, is there a time frame that they can appeal this? If she batted or played defense but now is waiting for the next half inning, is she in the game? Dave
