I will certainly make a bold statement regarding the defensive abilities of Boston Red Sox catcher Christian Vazquez in that he is the best defensive catcher I have seen in a Boston uniform, and that includes Tony Pena. That is made with a unique small sample that amounts to about one full season of baseball service, but it is enough to convince me.
Vazquez made a world of difference when he caught Steven Wright after Ryan Hanigan went on the disabled list. The passed ball situation diminished greatly and that came as no surprise.
