Walter Johnson was a good hitter, at least by today's standards. Pinch hitting was rare and only a decade or two before he broke in, pitchers were expected to play in the field when not pitching, due to small rosters. But still, it seems odd that anybody would decide to feature the hitting of the best pitcher in baseball. Johnson was well established by 1921. Are there other cards with Barney batting?
