this was a benefit tourney that was all weekend, going by ASA rules. in our last game on sunday night, we had a close play where the second runner (batter) on base came in right behind the first runner, (who started out at 2nd). they called the 2nd runner out because he stated that there was a slide rule at home plate. ironically, it was the first time we (or anybody in attendance) had heard that mentioned all weekend, and earlier in the day, one of my players got hit by a thrown ball running in to home plate but was still called safe, and scored a run. I was only asking because it sounded odd to me and i didn't argue it due to the fact that it was a benefit tourney. The same umpire both mentioned games also, and he is a seasoned vet of 20+ years umpiring i was told.
thank you for your answers guys!
