We’ve all heard about it. Under the Mike Hazen era, the Arizona Diamondbacks have made a strong, concerted effort to emphasize pitch framing. That’s one of the main reasons why the team has made moves to get Jeff Mathis, John Ryan Murphy, and Alex Avila while letting Chris Iannetta sign with Colorado.
Quantifying pitch framing data seems difficult. There are two websites (Baseball Prospectus and StatCorner) that assign “runs” to individual catchers based on their pitch framing data, but they don’t provide the details or anything on a team-wide level.
