A wild pitch in baseball is a charge given to a pitcher whose throw was so erratic that the catcher is unable to control it properly.
A wild pitch can either be a pitch that cannot be caught easily within the catcher’s mitt, or it could bypass the catcher completely and travel behind them. If the ball goes behind the catcher, it could waste more of the defense’s time as they attempt to find and retrieve the ball, leading the runner to advance bases as a result.
Wild pitches can only be charged providing there are one or more runners advancing. If no runners are advancing, or if the catcher takes control of the ball quickly preventing any runners from advancing, the wild pitch will not be charged.
