[2] Sisler rose to a chief petty officer and served as a physical instructor at the Bainbridge Naval Training Center in Maryland.

[2] He then made his MLB debut with the Redbirds in April 1946, spending a full season for the eventual National League and World Series champions.

On the 1950 season's closing day, at Ebbets Field, with the game tied at one, Sisler hit a tenth-inning, opposite-field three-run home run against the Brooklyn Dodgers that led to the "Whiz Kids" Phillies winning the club's first National League pennant in 35 years.

The home run (coupled with his slugging five years earlier in the Cuban winter league) made Sisler world-famous in baseball and literary circles when Ernest Hemingway immortalized him in his novel The Old Man and the Sea.

"[4] His father, Hall of Fame player George Sr., had become a scout for Brooklyn after his own playing career ended, and served in that capacity when Dick Sisler hit his pennant-winning home run.

Earlier, in 1946, he had gone hitless in two at bats as a pinch hitter for the Cardinals in that season's Fall Classic, but picked up a World Series ring when the Redbirds defeated the Boston Red Sox in seven games.

In 1967, while serving as the Cardinals' first base coach, Sisler earned his second World Series ring when St. Louis again defeated the Red Sox in seven games.
