It means that a small animal must be sacrificed to the ba<x>seball gods.<br />
One half of the ball must then be cremated and eaten by a 200kg ninja, the other half will be inserted into the anus of weird looking hobbo.<br />
Thus is the Gospel of Bullshit.
A damaged ball is considered to be the same as a ball that hit an obstruction in the field of play. It is declared a dead ball. It counts as a foul ball/strike against the batter.
