I should have mentioned in this last half inning the winning team's manager very slowly used 2 of his 3 mound conferences to stall for time (don't have to pull pitcher until 3rd visit).
USA and USSSA both have the same wording, that there can be three charged defensive conferences "without penalty".
USSSA reads "After three charged conferences...the pitcher shall be removed"
USA spells it out further, that "on the fourth and every subsequent conference the pitcher shall be removed"
I don't do any official USSSA, but I would think "three...without penalty" plus the "after three" would imply the same meaning as the USA explicit "on the fourth..."
