Fake bunt/swing..
I'm surprised to see how many people oppose this...
I coach it pretty regularly. Drag bunts, then sac bunt, show sac bunt and pull back to swing, show sac then pull back and then actually drag bunt, show sac bunt, and then push the ball past the charging corners...This is all part of our short game. We will take our opponents mentally out of the game by worrying about whether its safe to crash or not. If they stay back, we drag. If they crash we push bunt the ball past them or swing away. When they see that bat come back to swing, they freak out and start to back peddle, all focus has shifted into their safety and not winning the play.
There is strategy to it, and at 14U it is not as big a deal because the players are more softball "savvy", but if I called for a fake bunt-swing and my batter drilled a charging 3B in the face with a line drive, I would probably never forgive myself. Yes, accidents happen, but I am not going to implement a "strategy" that could get someone hurt.....that's just the way I roll!
I remember another time at 10U, when we played "up" in a tournament. The opposing coach came up to the HC and myself before the game started and pointed out his two biggest girls and said "those two are NOT going to bunt, play your 3B behind the bag when they are at the plate".....needless to say we did, and both those girls could knock the cover off the ball (my DD hung a curve ball over the middle of the plate that I swear went 275 ft and was still rising when it cleared the 200 ft fence), anyway, I thought it was a classy move by the opposing coach and we appreciated him taking the safety of 3B into consideration......
