About Balks

A balk is an illegal move by the pitcher immediately before windup or during the pitching motion. Most illegal moves involve a pitcher pretending to pitch with no intention of doing so, done to try and trick a baserunner into leaving the base and becoming an easy out. Balks are only called when there are runners on base; when a balk is assessed, all baserunners are awarded the next base, including runners on third who would then score. The batter is not awarded any bases and their plate appearance continues with no change to the count. Generally, for Balks, lower is better. (Source)
