On July 18, 1961 — At Busch Stadium, Bill White ties Ty Cobb’s 49-year-old record by collecting 14 hits in consecutive doubleheaders as the Cardinal first baseman goes 3 for 4 in both games of a doubleheader sweep over the Cubs. Yesterday, the future National League president had gone 8 for 10 in twin bill action also against Chicago.
