mental locker. When a player arrived at the clubhouse at Wrigley Field, or the visiting ballpark, he opened his mental locker. With each article of clothing he removed—his jacket, his shirt, his belt, one sock, then the other—he let go of a problem or a personal concern. By the time he had changed from civilian clothes into his uniform he had shed all his distractions and personal concerns and was focusing on the present. He was in the right time zone and the ideal state of mind to experience success on the field.
