Plot hole: The game in Houston is only 4 innings. If it almost got called after 2 innings, it's obviously pressed for time. Although called safe for the win, if Kelly was called out at home plate at the end of the 4th, the game would have ended in a tie. No extra innings would be allowed for sure this time due to time factor, so how would a winning team be determined to play in Japan?
Suggested correction: This isn't a plot hole, it's a question. Asking "what would have happened if..." isn't a valid plot hole. The writers had no need to explain "what if" scenarios since they never would have occurred. However, to answer your question with plausible answers; 1) The Bears HAD to win in order to go to Japan and thus a tie would mean the Toros played Japan (like a champion retaining his title after a draw in a title fight). Or 2) They played a 2nd game at a later time.
