I was an assistant for a few years and I had the pleasure of watching a true pro in action. He had a way of walking to the mound and taking the ball from a pitcher - which by the way, was a difficult thing to do.
Pitchers will try to talk you out of it. Their winners, and winners always want the ball - always.
So, during my first season with the man, I’d watch him go to bump, a second or two later, coming off the rubber was one pitcher while running in from the pen was another. No conversations, no waiting, nothing.
But what surpirsed me, was the expression on the faces of the pitchers coming in. They all had this smirk on their face.
Finally, I couldn’t stand the suspense any more. I made my way over to one man that was sent in, and while wiping his face with a trainer’s towel I asked him what was the smirk on his face for - he was just yanked out of an inning.
Here’s how this coach did it:
He’d walk out to the mound, climb the bump, stretch out his hand and extend his index finger, then he’d look at the pitcher and say… " go ahead, pull my finger."
Enough said, the guy was gone. It also broke the tension. In fact, later in my career, I use to use it. It worked like a charm.
