A passed ball is a charge given to a catcher in the case that they fail to catch or hold the ball on a legally thrown pitch that they otherwise should have had under control, and as a result, at least one runner was able to advance one or more bases.
Who Decides Whether a Play Qualifies as a Passed Ball?
It’s the responsibility of the official scorer of the game to deem whether the play qualifies as a passed ball. If they decide that the ball could have been controlled by the catcher with ordinary effort, they will charge the catcher with a passed ball. If the passed ball occurs on the third strike and the hitter reaches first base, the official scorer will also score a strikeout in addition to the passed ball.
