Strikeout to Walk Ratio or K/BB is a pitching statistic that measures the number of strikeouts a pitcher throws for each walk the pitcher allows. K/BB gives an indication of the ability of a pitcher to control their pitches.
More about Pitcher Strikeout to Walk Ratio Leaders
Strikeout to walk ratio leaders are those who have the highest proportion of strikeouts against for every walk they allow. With the rapid increase in strikeouts in recent years leaders in this category have seen higher and higher rates nearly every year (with a modern day record set in 2014 by Phil Hughes with an outstanding ratio of 11.6). Most league leaders will have a ratio of approximately five or six strikeouts for every walk allowed, though a pitcher with a ratio of four or higher is generally a very effective pitcher. Pitchers can of course score high on this measure by doing everything they can to limit the number of walks against (which is what Hughes did in 2014 by allowing an astoundingly low sixteen walks in over 200 innings pitched).
