Petti: Calling strikes on the edge of the plate

From SABR member Bill Petti at FanGraphs on July 24, 2013:

When we last left our discussion of Edge% we were looking at the differences in the rate of called strikes based on the count. Generally speaking, umpires were less likely to call strikes on the Edge in pitcher-friendly counts and more likely to give those calls in hitter-friendly counts.

While we learned a bit from that analysis, it was really just the tip of the iceberg. There are a number of additional ways to cut the data, and that is the focus of this article. Count is just one dimension when we are thinking about what might influence the likelihood of close called strikes. There are a number of additional dimensions we can layer onto count, and that’s precisely what I show in the (admittedly large) table below.

 The data below represents the called strike percentage on taken pitches thrown to the Edge at the league level, cut by count as well as other “splits”, including: pitch type, type of platoon matchup, pitcher and batter handedness, and inning. Like the previous article, the numbers here include pitches thrown between April 1 and July 10 of this year.
