On May 3, 1951, Rookie Gil McDougald of the New York Yankees ties a major league record by driving in six runs in one inning. McDougald hits a grand slam and a two-run triple in the ninth inning of a 17-3 demolition of the St. Louis Browns at Sportsman’s Park. McDougald’s record will eventually be broken by Fernando Tatis of the St. Louis Cardinals in 1999.
