Plate appearances per strikeout
In baseball statistics, plate appearances per strikeout represents a ratio of the number of times a batter strikes out to their plate appearance.
This statistic allows a defensive team to examine the opposing team's lineup for hitters who are more prone to strikeout. Such players, when batting, are typically more aggressive than the average hitter. This knowledge permits the pitcher to approach the batter with more pitching options, often throwing more balls out of the strike zone in the hope that the batter will swing and miss.
The number of this statistic can be calculated by dividing a player's total number of plate appearances by their total number of strikeouts. For example, Reggie Jackson collected 2,597 strikeouts and 11,418 plate appearances in his 21-year baseball career, recording a 4.39 PA/SO, which suggests that for every 4.39 plate appearance Jackson had one strikeout.
