Our guest this week was considered by many who played for the Chicago White Sox as the best batting practice pitcher of all time. Glen Rosenbaum signed with the White Sox in 1955, but never made it to the Big Leagues despite a career record of 95-45. Listen to Glen, or "Rosie" as his teammates referred to him, talk about the reason Manager Al Lopez never brought him up to the Majors. Rosie also shares many stories of his days in baseball, which lasted from 1955-1965 as a player, then until 1998 as a coach/traveling secretary. Enjoy this look Back When There Was Baseball.
