The son of major league pitcher Ewart “Dixie” Walker and brother of 1944 NL batting champ Fred “Dixie” Walker, Harry is the only player to win a NL batting title playing for two teams in the same season (and the Walker brothers are the only major league siblings to each win a batting average crown). Harry was hitting .200 through May 3, 1947 when the Cardinals traded him to the Phillies. He pounded the ball for a .371 average the rest of the way to finish at .363. It was to be his only outstanding season.
It was Walker who, in Game Seven of the 1946 WS, drove in Enos Slaughter from first base with the winning run to defeat the Red Sox. He was called Harry the Hat because, at the plate, he would adjust his cap after every pitch. As a result of his tugging, he went through 20 caps a season. He became a manager, taking over the Cardinals from Eddie Stanky for most of 1955 and pinch hitting nine times. He managed Pittsburgh from 1965 through mid-1967 (twice bringing them in third) and Houston from 1968 through late 1972. He continued in baseball as a batting coach.
