Henry Eli Staley was an American professional baseball player who pitched in the major leagues from 1888 to 1895. He played for the Boston Beaneaters, Pittsburgh Alleghenys/Pirates, Pittsburgh Burghers, and St. Louis Browns. On June 1, 1893, in a game against the Louisville Colonels, Staley had nine runs batted in, a record for most RBIs in a game by a pitcher. The record stood for over 70 years until equaled by Atlanta Braves pitcher Tony Cloninger in 1966.
