If Williams had left Zimmermann in for another guy to get on base or worse, there would have been even more pitch forks out for him. He pulled him at the right time. The only question is whether he should have been pulled him sooner. It really shouldn't even be controversial. Zimmermann had some good pitches against that last batter, but he also air mailed one high and grooved one that was hit in the upper deck only a few feet foul.
