No, it's not 100% Zambrano's fault. Barrett definitely was in the wrong as well. They're both to blame.If Zambrano actually had the ability to control his emotions and not act like a baby, this would have never happened. Zambrano came into the dugout and started mouthing Barrett, not the other way around. It's his fault. Again, the point is that it's not ALL his fault. Largely, yes, but Barrett without question was in the wrong as well.
