Part of the game’s statistics, a Base on Balls per Strike Out (K/BB) is a measure of the number of a pitcher’s strikeouts divided by bases on balls recorded. The ratio is a reflection of the pitcher’s control over each pitch. A power pitcher is someone who has obtained a favorable K/BB ratio or strikeout-to-walk ratio. A higher ratio means the pitcher has mastered the strike zone and has exhibited great discipline on each play.
