One Aspect of Catcher Defense

Over at Fangraphs David Appleman has a piece on pitch blocking by catchers. He creates two new statistics. One is CPP, the expected number of passed pitches. The other is RPP, runs above or below average in blocking pitches. The usual suspects do well on this measure of catcher defense, Yadier Molina, Brian McCann, Matt Wieters #!!%$##!. Note that Rod Barajas looks pretty good on this metric as well. Also note that Doumit (what a shock!) and Chris Snyder look pretty bad. The number before each player's name is their 2011 rank in RPP.

The swings here are not huge, on the order of 10 or so runs over the course of a year. The open question is how many wins one adds by upgrading defense at catcher and short. Got me.

Name 2011 CPP 2011 RPP
1 Yadier Molina 223 19.9
2 Brian McCann 227 16.8
3 Carlos Ruiz 131 14.9
4 Matt Wieters 125 13.3
5 Humberto Quintero 103 13.1
6 Rod Barajas 141 11
39 Michael McKenry 24 1.1
119 Jake Fox 6 -0.8
129 Jason Jaramillo 35 -1.2
142 Dusty Brown 5 -1.9
143 Jose Morales 17 -1.9
149 Ryan Doumit 130 -2.5
163 Chris Snyder 105 -4.2
