The Spiegel Grove Squires, the vintage base ball team at the Hayes Presidential Library & Museums, will play the Great Black Swamp Frogs on the lawn behind the Hayes Home. The Squires bring to life base ball in the 1860s, when the sport – spelled with two words at the time – became organized with standard rules of play for clubs. Members of the Spiegel Grove Squires are volunteers. They have studied and learned the methods of play used in the 1860s, including playing bare-handed. Players are called ballists, and they wear period-style uniforms and adopt the language of 19th-century base ball during their matches, as games were called during the 1860s. The Squires are sponsored by Whirlpool Corp.
