What is K/9 Strikeout Rate?
The K/9 rate, or strikeouts per 9 innings, represents the average number of strikeouts a pitcher have in a 9-inning game. This metric is widely used in baseball as it allows pitchers and coaches to know a pitchers strikeout capability independently of the number of innings they pitched.
How to Calculate K/9 Strikeout Rate?
To calculate K/9, you only need two values: the total strikeouts and total innings pitched.
For example, if a pitcher has 60 strikeouts over 30 innings pitched, their K/9 would be:
= (60/30)*9 => 18
