On August 31, 1937, Detroit Tiger Rudy York smashed his 17th and 18th home runs of the month, breaking the major league record previously held by Babe Ruth. The rookie catcher’s round-trippers on the last day of the month helped the Tigers defeat the Senators at Navin Field, 12-3.
York’s one-month home run record would last until 1998, when Sammy Sosa hit 19 in June.
