ASA Slowpitch rule

[nkva]

Here is a rule question for ASA Men's slowpitch: Team A is the home team and leads after the 5th inning by three runs. In the top of the 6th inning Team B scores 5 runs to take a 2 run lead. Team A starts the bottom of the 6th and after a batter reaches first and an out is recorded, the timer for the field lights goes off and shuts down the field lights, thus ending play.

The Ump says that Team B wins.

If the game were called due to rain, I would think that you would call the game based on the score of the last completed inning if there were 5 or more complete innings played.

There was talk of making us replay the last 2 outs of the 6th inning.

Anyone know the rule?

Thanks
