When John Clarkson joined the "club" in May 1887 he became the first of many from Chicago to do so. Two months later he became the first and only pitcher in history to do it twice in a season and remains the only pitcher to do it twice over the course of a Major League career.
Did you know that the July 3, 1966 game is actually quite legendary as the home run hit by Cloninger versus Sadecki was a grand slam in the fourth inning AND Tony had already hit a grand slam during the first inning versus Bob Priddy?
The 1887 Chicago White Stockings only had four full time pitchers on their roster and Jimmy Ryan, who apears above on 05-13-1887, was not one of them — he was a starting outfielder who had one-hundred twenty games in the field in 1887, three more at second, and eight on the mound.
