Patrick Rock has found what may be Cool Papa Bell’s first appearance (as “J. Bell”) in a printed box score, pitching for the Compton Hill Cubs in a 1921 doubleheader (St. Louis Argus, May 6, 1921).  The other Bells here were his brothers (probably named Lee, L.Q., Sam, and Robert, with maybe Fred pitching in the first game).  Patrick reports that J., L., S. and R. Bell all appeared with the Cubs throughout the summer.
