I prefer to leave this play out of my playbook. It's a high risk/low reward play. I can't think of when it last worked, but I can think of many times the ball ended up in left field with a run scored.
The reward is also high i.e., erasing a runner from third, at best, or shortening runners' leads, at worst. Its the difficulty of execution that is the drawback, but the probability of proper execution increases as they become more experienced. Running the pick off options without having the catcher throw sometimes is enough to curb the runners' aggressiveness. But if the runners continue to take liberties and there's an out begging to be made (and you've practiced the plays), let it fly!
