He moved to the Chicago American Giants in 1926 and hit .268 that season. In 1927, Russ batted .350 and was 8 for 35 in the 1927 Colored World Series.
Russ switched to shortstop in 1928 and hit .405 to win the NNL batting title, and hit .407 in the postseason to help Chicago to the league championship. In 1929, he hit .386 to finish second in that category, and hit 11 triples. He fell ill with tuberculosis early in 1930 and died in August of that year. His lifetime batting average in the Negro Leagues was .350.
