What is Strikeout to Walk Ratio?

K/BB is a baseball ratio used to show a pitcher’s number of strikeouts for each walk that they allow. A higher K/BB generally indicates better pitching ability (as there are more strikeouts in relation to walks allowed).
It is the opposite of the Walk to Strikeout Ratio (BB/K which is used to evaluate hitters.

How to calculate K/BB

In Baseball, on Strikeout to Walk Ratio is calculated as follows:

K/BB = Strikeouts / Walks


If a pitcher throws 143 strikeouts and in that time allows 64 walks, then:

K/BB = 143 / 64
K/BB = 2.23

This pitcher’s K/BB is 2.23 – they pitch approximately 2.23 strikeouts for each walk they allow.
