You know I thought so as well, but it seemed like Lou made up his mind to put the squeeze on before Fontenot's AB. If that was the case, you want to bring a good bunter to the plate, hence Fontenot instead of Fox. Sure, he could have used Blanco but that would have just been too obvious he was going for the squeeze. Fontenot had a perfect pitch to bunt and he just missed it. He deserves more of the blame than Lou.
