On June 22, 1948, Stan "The Man" Musial rapped out five hits in five trips to the plate in Boston, as he led the way to a 5-2 victory over the hometown Braves. All of Musial's hits were singles, and the fifth and final one of the day broke up a 2-2 tie in the ninth that brought Red Schoendienst, and Harry Brecheen into score. Enos Slaughter followed Musial with another RBI single that gave the Cardinals the three run lead that would hold up as Brecheen locked down a complete game victory by setting the Braves down in order in the bottom of the ninth.
Musial went onto win the National League MVP award that season. It was the third time he took home the honor. He had picked up five hits in a game four different times that season which tied a mark set by Ty Cobb in 1922. According to Mark Tomasik at Retrosimba.com that is a feat that has only been matched twice since. Mark did a great job on this piece about Stan's last five hit game of that season which came on September 22nd. It also covers a little bit of the other five hit games, and has some great facts as well.
