More on the Double Switch

As often happens a member of SABR added more information to the question of the first double-switch in major league history. Maria Vaccaro noted that she thought it had been accomplished in the 19th century but the first actual citation she could produce was for 8/2/1906 when Highlander manager Clark Griffith put himself in as a relief pitcher in the eighth inning at Detroit and also put catcher Ira Thomas in. Before the switch the catcher's position batted 8th and the pitchers position batted 9th. Griffith inserted himself in the 8th slot and put Thomas 9th.
