Baseball is rife with superstitions, my informant is a long-time player and as a pitcher he describes to me the longest-stranding baseball taboo.
“You don’t step on the white foul line when taking the field, ever, not just pitchers, but all players, but especially pitchers. When I go out to the mound I jump over it with my right foot, and always my right foot. It’s bad juju if you step on the line, nobody steps on the line, it just isn’t done. It’s bad luck. It’s always been that way. I don’t know who I learned it from, it’s just always been done as long as I can remember.”
Baseball superstitions, rituals, charms, and taboos usually are surrounding those circumstances which are not totally in the player’s control, that is pitching and hitting usually. This particular superstition is not stepping on the foul line when taking the field. It is quite an old superstition that has no particular origin with a certain player, but one players of all caliber pay attention to. It is supposed to prevent bad luck in a game when one play can change the entire game. Because it is so old and established as a taboo, players simply adhere because all those players before them have done so, so it must work, and the players will do anything that works. One bad pitch or one great hit and the game could turn for the worse. A pitcher can do all he can to play perfectly, but he cannot control the batter’s actions, therefore this leaves a lot of room for superstitions. It is human nature to want to control one’s surroundings and this is just a little taboo that allows a player in his mind to control the outcome however small.
