New York fans are rightly lauded as passionate and informed, but there’s always more to learn about our national pastime’s history. The Mid-Atlantic Vintage Baseball League (MAVBBL) comprises clubs from the Empire State through Virginia who celebrate the sport’s mid-19th-century roots. New York lays claim to four squads: the New York Gothams, Brooklyn Atlantics, New York Mutuals and Brooklyn Eckfords. The league organizes fixtures played according to 1800s rules; some of the old-school guidelines include no gloves, balls caught on bounces for outs and a mound significantly closer to home plate, all of which made for a faster-paced, if somewhat more injury-prone nine innings back in the day. Players wear classic, baggy wool-and-flannel uniforms and educate spectators about how the sport has evolved. For instance, attendees at New York Gothams home games on Governors Island can ask questions and touch the equipment, and in some cases even wear one of those stifling jerseys and get on the field. So while the Mets and Yankees won’t face off again this season, you can still experience some throwback rivalries when the Gothams take on both the New York Mutuals (July 27 noon) and the Brooklyn Atlantics (Aug 24 noon).
