From 1900 through 2003, 952 players appeared in only a single major league game. Of these, 86 were starting pitchers and Dick Bass, at age 33, was the oldest. His career is of special interest because he managed two minor league teams, coached a team to the World's Amateur Championship, and was a manager of the Daisies in the All-American Girls Professional Baseball League. Also, a recording of the radio broadcast of part of his game survives.
