Experiencing inflammation in his right index finger, on June 16, 1884, right-handed pitcher Larry Corcoran of the White Stockings pitched ambidextrously in a game against the Buffalo Bisons. He alternated arms throughout, though I haven’t been able to figure out if he switched arms every pitch or every batter. He would keep this up for four innings, before being moved to shortstop, as Chicago lost 20-9 in Buffalo.
