on the field nor intentionally cover the pitcher’s or home plate.
A.R. 2.15.2: Deliberately covering a line with infield material is considered
removing the line.
EFFECT—A strike shall be called on the batter if the offense intentionally
violates the rule and a ball shall be awarded to the batter if
the defense intentionally violates the rule.
