Back when I coached 11-12 AABC, we had a good game going. In the bottom of the 5th the other team had one on 2nd and the batter had a 2-1 count, and 1 out. Now I noticed that the runner on 2nd wasn't getting back to the bag after every pitch. So, I called timeout and had all my IF come in. I told the pitcher to make a pitch and when he received the ball back from the catcher to not step back onto the rubber. He was to turn around and throw the ball to the SS and, hopefully, tag that runner out. I was hoping that the runner would get surprised and freeze, easy out. Well, the pitcher throws the ball and it's a called strike. Catcher throws it back and pitcher grabs the ball out of his glove and throws to the SS. Just like I hoped, the runner froze. But instead of tagging the runner, the SS showed the runner the ball and waited until she was back on base before tagging her. I was angry, but I laughed it off. We did win that game, BTW.
Dumbest coaching move. We were in the AABC state tournament and it was bottom of the 7th. We were up one run. I wasn't the HC, but assistant. I did coach another team, but we didn't make it. Anyway, I used a play where the pitcher and all of the IF and catcher would come in. Just as in the above story, runners sometimes didn't get back or would come off the bag after the ball was thrown back to the pitcher. So, the opposing team had two on, 2 outs, and their best batter up. So, I asked the coach if he wanted to try it. He calls a timeout and I explain the play. I told the pitcher to make a pitch and when the catcher throws it back to make sure he stays off the mound and make a throw to SS to try and get the runner out at 2nd. Everything went as planned. The pitch was a called ball and the catcher throws the ball to the pitcher. Sure enough the runner at 2nd comes off. Pitcher throws to SS and SS tags runner. But, while this was going on the HC called a TO. The TO was granted as soon as the pitcher received the ball. HC wanted to make an OF change.
The batter ended up hitting the ball to the OF, where the one that was put in and he missed it. Ball goes to the fence and both runners score to win the game. So it goes... LOL!!
