Watched the Triple Crown World Series championship game for 9U from Steamboat Springs this weekend on TV. There was a play where batter hits the ball to the OF. Outfielder catches it and R2 tags up appropriately and runs to 3rd.
Time was called (can't remember why) and defense wanted to appeal that the runner left early. So F1 got on the rubber with the ball, stepped off, turned and threw to F4 who stepped on the bag and PU gave safe sign.
While this went on, R2, who was on 3rd, ran home and scored. But umpires ruled that ball was not in play and he had to go back to 3rd.
Announcers didn't mention why the ball wasn't live. The ball has to be put in play for an appeal after a dead ball, so why couldn't runner go home at his own risk?
They play high school rules, the announcers said.
