15-16 year olds, Pitcher struggling a little Coach calls for a visit, I yell "Time Coach this is your first visit" , He points and gives me a nod, He returns to the dugout and play continues, Later that same inning, the coach calls time again and now wants to see the catcher, He tells the catcher something and then the catcher returns to the plate area and before the ball is put into play, runs out to the mound to relay what the coach just told him, I in turn go to the coach and inform him that this is considered your second visit and lets remove the pitcher, he gets concerned and says I'm wrong, any thoughts
