Scenario:
Championship game, so 7 innings with no time limit. Team A up 3-0 until Team B power hitter knocks a 3 run homer. Team B scores one more run and is up 4-3 after six innings. Getting very dark and no lights on field, but the next inning is started. Team A scores a run in the top of the 7th to tie, and getting darker still. Bottom of 7, team B gets a lead off double and power hitter from earlier up to bat. Team A tells umpire they want to IW power hitter and umpire tells her to go to first base, as she has been walked. Team B doesn't score so still tied after 7, and now it really is tpo dark to play. Umpire calls game, and then awards team B the win/championship, stating that the score reverts back to the inning that finished in the daylight.
Questions - can an intentional walk just be "awarded" without having to throw the 4 balls, thus taking away the opportunity for a wild pitch or passed ball, as IWs are pretty rare and can be difficult to execute.
Is the reverting back to daylight a real rule, or is it a TCS rule, ASA rule, or made up on the spot?
Thanks in advance.
