Among Schaefer's legendary antics are diversionary tactics with umbrellas, raincoats and galoshes, to get games canceled on account of the weather. In one story he wears the outfit out onto the playing field, in another he wears it to the plate during a drizzle, but when the umpire sends him back to the dugout to take it off, the rains begin to pour, forcing the umpire to indeed call the game.
An account of Schaefer wearing a raincoat onto the field occurs in the July 4, 1906, edition of The Washington Post. It is not known whether he wore it on offense or defense.
