He was the first Chicago Cubs player to homer in a night game, which he did on July 1, 1938 while playing at Cincinnati. He drove in 5 of the 9 runs in the Cubs' 1938 World Series loss to the New York Yankees. His .500 batting average (6-for-12) led all Yankees and Cubs regulars in the series, although he did not appear in Game 1. On October 8, 1938, in Game 3, Marty's solo home run was the first home run hit in a World Series game by a native Sacramentan.
He left baseball in 1941 to join the military; after his military service, he opened a popular restaurant in Sacramento on Broadway. After his death in Sacramento in 1984, the restaurant continued operation under new ownership, until a fire destroyed the building on June 25, 2005. The building was destroyed, but much of the memorabilia was saved.[2]
