OAKLAND, Calif. — The image of fireworks lighting up the sky over Greenman Field in Oakland is still bright in Cubs second baseman Nico Hoerner’s memory.
As a kid, Hoerner always looked forward to playing night games at the fields a few blocks from where the Athletics play. And none was more epic than 10-year-old Hoerner’s Mustangs taking on the rival Bulldogs as the A’s firework show turned the scene into something straight out of ‘‘The Sandlot.’’
