I promised to look into the frequency of wild pitches and passed balls depending on whether Molina or Zaun was behind the plate.
Prepare to be astonished.
The Passed Balls are easy of course - Molina has been charged with 6, Zaun with 2. As for the wild pitches, we have to dig into the Game Logs. And this is what I found:
Burnett (2) - Molina, Molina
Chulk (1) - Molina
Downs (4) - Zaun, Molina, Molina, Molina
Towers (1) - Molina
Frasor (1) - Molina
Halladay (1) - Zaun
Janssen (2) - Zaun, Zaun
Lilly (3) - Zaun, Molina, Zaun
Rosario (2) - Zaun, Molina
Ryan (1) - Zaun
Speier (1) - Molina
Tallet (1) - Zaun
The total is 11 with Molina catching and 9 with Zaun catching. The total Advancement Events, therefore, is Molina 17 and Zaun 11.
Except - Molina has played a fair bit more - 407.1 innings behind the plate, as compared with 232.2 for Zaun.
So Molina lets one get away - a passed ball or a wild pitch - every 23.9 innings.
And Zaun lets one get away every 21.1 innings.
Perhaps not astonishing, but mildly surprising, no?
