On Saturday, local author and La Salle professor emeritus John Rooney is holding an event for his book Bleachers in the Bedroom: The Swampoodle Irish and Connie Mack, about the old Irish neighborhood and the trials and tribulations of the Philadelphia Athletics, who played in the city until 1954. The book is named for the neighborhood's practice of watching the games at Shibe Park, at 22d and Lehigh, for free from atop nearby rowhouse roofs and upper-story bedrooms. (Team owner Connie Mack attempted to curb the practice and create a baseball dynasty. Neither effort quite worked out.)
