The photos below are from the Washington Evening Star and the Washington Post respectively. Unfortunately, they do not show the Washington "W" on the cap.
Perhaps you can try identifying Fisher in the 1924 Senators team photo in the link below. It seems to me that he bears a resemblance to the player in the top row standing second from the right. Fisher was gone by the time the Senators were in the World Series, but it seems unclear as to when this photo was taken.
