Plate Discipline Stats

About two years ago I attempted to delve further into plate discipline with two articles: Dissecting Plate Discipline Part 1, Part 2.

And then a year later I took an additional look at plate discipline: More on Plate Discipline

All batters now have plate discipline stats available dating back to 2005. Here’s what they are:

• O-Swing%: The percentage of pitches a batter swings at outside the strike zone.
• Z-Swing%: The percentage of pitches a batter swings at inside the strike zone.
• Swing%: The overall percentage of pitches a batter swings at.
• O-Contact%: The percentage of pitches a batter makes contact with outside the strike zone when swinging the bat.
• Z-Contact%: The percentage of pitches a batter makes contact with inside the strike zone when swinging the bat.
• Contact%: The overall percentage of a batter makes contact with when swinging the bat.
• Zone%: The overall percentage of pitches a batter sees inside the strike zone.

What you’ll want to know is the major league averages for each stat:
