What was the outcome of last year’s championship game between Tangerine and Lake Windsor?

From the text:

As we drove past the packing plant and into downtown Tangerine, Henry D. started to tell me about last year's game with Lake Windsor. "It came down to the last game last year, too. That's why they're our archenemy now. They came here last year with the same record as us, 9–1. They beat us in the last game, on our own field."
