Well first do you practice the move? They teach 5 different moves at UNF, 1st, always when someone gets on, just come set and at about 80% go over. This gives you a little feel as to the throw, a little practice...lets you see how the runner is paying attention and is going to react and it lets them know you're paying attention.
The first move is as you lean in before getting set just on your first move go to first. 2nd is just as your hands touch as you come set, 3rd is your A numba 1 move, come set hold it and go to 1st, 4th is just hold it til someone calls time...this messes up the running game and many times you'll be able to be tipped that the guy is leaning, 5th is a balk, but seldom if ever called, buckle your front knee and then go. You also can work in the step off and go and the one I mentioned as the gain ground then pick...there ya go, 7 different looks..If you practice with your 1b you can become death to the running game and maybe get yourself an out or two per game. Practice it once or twice a week. Let us know if you have success.
