The Cardinals began 1963 by winning 10 of their first 15 games, as Musial posted a .237 batting average. He set a new major league record for career extra-base hits on May 8 and improved his batting average to .277 by the end of the month. Making his 20th All-Star appearance and 24th All-Star Game appearance on July 9, 1963, he pinch-hit in the fifth inning. Asked by general manager Bing Devine on July 26 what his plans were, Musial said that he would retire at season's end. He waited until the Cardinals team picnic on August 12 to publicly announce his decision, hopeful he could retire on a winning note.
