That's why you can't wait until DBT, unless he immediately goes there. Being the end of the game, you can't be sure he'll even re-enter the dugout again - he might head straight for Dairy Queen
Meanwhile, the defense has left the field, packing their gear, drifting off to meet mom and dad....no, clearly this won't work. Judgment call....allow a little time for a coach or someone to yell, clue him in, but once the dugouts empty and I've got a mob in the middle of the diamond, I have no heartburn calling him out.
JMO, your mileage may vary!
