Lynch: Pitch framing measures added to

From Mike Lynch at on March 8, 2018:

Our friends at Sports Info Solutions (formerly known as Baseball Info Solutions) have provided us with a pitch framing measure back to 2011, which we have added to Baseball Reference. Before I explain any further, if you’re unfamiliar with the concept of pitch framing please read Mike Fast’s 2011 article on the topic and Ben Lindbergh’s 2013 follow up.

The stat that we have added is called Strike Zone Runs Saved. It represents the runs saved by catcher framing. In our tables, it’s labeled RszC and it’s available from 2011 to the present. While this statistic is a potential component of Defensive Runs Saved (and therefore WAR), please note that we have elected to not integrate this number into DRS (or WAR) at this time. We may elect to do so in the future, but for now we agree with Bill James’s stance that waiting for further research is a good idea.
