Baseball spring training is happening, so this photo from the March 11 1930 edition of the Toronto Daily Star seems relevant:
Perhaps pitching recruit Reginald Baker didn’t pay close enough attention to Connie Mack, as he never pitched in the major leagues. He last appeared in organized baseball in 1937, after four years away. I could find out nothing else about him, other than that he was listed at 6’3″ and 195 pounds, which is quite large for that era.
Connie Mack, the Philadelphia Athletics’ “perennial manager”, continued to run the team for another twenty years, finally quitting the game in 1950 at the age of 86. He was inducted into the Baseball Hall of Fame in 1937, despite still being active. Like Baker, he was tall for his era – he is listed at 6’1″.
