Did you know that umpire hand signals in baseball exist thanks to William Ellsworth Hoy, a famous deaf player who was active from 1888 to 1902? He developed his own system of hand signals for the third base coach to use for "strike" and "ball," so he could tell what call was made when he was up to bat. When an umpire lost his voice due to a larynx injury in 1906, he adopted Hoy's signals, and the rest is history! #DeafHistoryMonth | Mercy
