Perry used his reputation to psyche out the hitters as well. As he looked in to his catcher for the pitch selection, Perry would touch various parts of his head, such as his eyebrows and his cap. In this manner, he may or may not have been applying a foreign substance to the ball on any particular pitch. Reggie Jackson was so upset after striking out against Perry one time that Jackson was ejected from the game. Jackson returned from the dugout with a container of Gatorade, splashing Gatorade onto the field while yelling at the umpire that Perry should be allowed to use the Gatorade on the baseball.
