Yadier Molina, allowing all of 12 sb's at this point of the year is pretty damned impressed, as there are teams that have allowed close to 70.
So, how much is pitch calling, and how much are fewer SB, WP and PB's? Hard to say.

Did you read that article?

Also, it's a half of one season? Hardly enough data to come to a conclusion.
