Local baseball fans are accustomed to watching Sunday afternoon games and getting a beer at McCoy Stadium in Pawtucket or Fenway Park in Boston. But it wasn’t always this way. A new book by the Providence Journal’s deputy editorial page editor, Edward Achorn, describes how Sunday games and beer sales were once controversial. His book, “The Summer of Beer and Whiskey,” describes 1883 as the groundbreaking season that remade baseball as the national pastime. Achorn says he wanted to recount the story since that era of baseball history remains unknown even for many fans of the game.
