Not too long ago I was watching an APA match between a couple of low level players. Winner of the match goes to Vegas for the National singles in their level group.
It was a match with two women and one is a skill level three and the other is a skill level two. The three has to win three games and the two goes to two games. The score is hill/hill meaning they each need one more win.
The skill level three is at the table and is on the eight ball but she is hooked and decides to kick at the eight to the pocket that she marked. She does hit the eight ball, doesn't make it, but then scratches.
The level two players picks up the cue ball lines up for a shot on her remaining ball before the eight. She shoots and misses. The level three then says she is taking a bathroom break. While she is gone the level two player is informed by spectators that level three scratched and lost the game.
Understanding that both players are under pressure and probably unsure of what happened. When the level three returned from her break the level two called for the tournament director to sort things out.
When he came over and was informed of what happened, he asked the lever three if she had scratched and she confirmed that indeed scratch. He thought about it for a bit and then made the decision for them to play the game over. Me, not being involved, kept quiet. Was that the right call? Would you have said something?
The APA Tournament Director's word is final, so at this point whichever player won the replay will be able to compete in Vegas. If the 3 won only by way of replaying that questioned game, though, there may be an opportunity for the 2. The TD's call is in clear discord with the League's game rules. There is no scenario in which the three should have been allowed to make another shot, and no scenario in which the game should not have been concluded after that scratch on the 8 (any more than if two baseball teams end the 9th inning with a score of 7-4 lined up to play a 10th - it would be invalid as no additional play can occur at the conclusion of the game).
If the 3 ended up winning the replay and consequently the trip to Vegas in the 2's stead,
the 2 has a very strong case to appeal to the APA National Tournament Director to be afforded the opportunity to compete at nationals, inclusive of all of the travel assistance/hotel compensation that would normally have been afforded her. Of course, the tournament is in the beginning of May, so time is short - she should pursue such an appeal immediately.
Edit - on looking back at the OP, the argument cannot be made that the 2 missed the opportunity to call the foul, even if it did not stand and execute the end of the game on its own, as her shot cannot be shown as deliberate continuation of the game. Had she made her final ball before the 8 and then marked a pocket, it might be be strained to argue in favor of a replay, but as she did not, and did not allow the 3 to take another shot before she commented on the loss, there is absolutely no sustainable logic under the rules of the game by which the TD's call would be upheld on appeal. The 3 would not be removed from participation in the national tournament as it has already been granted, but the 2 would certainly gain entry.
