Team Deliberately not trying

[Gemini]

We have a couple of teams in our Open Men's ASA league that after they get ahead by a good margin, they swap positions, miss balls, trying to give the other team a chance to close the gap in the run rule. All they are wanting to do is bat again so they can score another 10 or 12 runs.

Had it happen last week. Team up by 11, I'm on the bases, the pitcher threw 8 straight balls which walked in 2 runs. Now the difference is 9, so we play the top of the inning, and this team scores 15 runs.

I cannot find this addressed in the rule book. Anyone have any ideas?
