Plate Discipline Stats

Posted By David Appelman On April 28, 2008 @ 7:20 pm In Site News | 16 Comments

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:

Season O-Swing Z-Swing  Swing  O-Contact Z-Contact Contact   Zone
2005     20.3%   68.0%  46.0%      51.8%     88.3%   80.8%  53.8%
2006     23.5%   66.6%  46.1%      57.4%     88.5%   81.0%  52.6%
2007     25.0%   66.6%  45.9%      60.8%     88.2%   80.8%  50.3%

All the location data is from Baseball Info Solutions and you can find all these stats in the player pages at the very bottom: Vladimir Guerrero
