I had almost the same play yesterday between two 18-gold teams. I was the BU behind F4, F6 fields the ball, takes 3 or 4 steps towards 2B, touches the 3B side of 2B bag, and R1 slides to the inside of the bag, taking F6 out completely. I look over at BR2, who was about 2 steps away from 1B. There was no question in my mind this was obviously intended to break up the double play - dead ball, 2 outs.
It was instinctive... like "you know it when you see it" kind of play. OC wanted me to "check with my partner"... uh, coach, my partner was 80 feet away. It's my call, and my partner's not going to have any information that would make me change my call. We're done.
Since that ended the inning, I trot out to my spot on the OF grass, and the coach follows me, still arguing at me "What do you want us to do, go in standing up?"
"Coach, that would be unsportsmanlike conduct, and if one of your runners do that, she
and you will be ejected."
No more chirping from the OC for the rest of the game. Probably because they wound up winning 7-0.
