In 1914 Sweeney stole 19 bases – the most ever by a Yankee catcher. He did the bulk of New York’s catching from 1910 through 1914. He reportedly played a role in star first baseman Hal Chase‘s fall from grace in 1913. Sweeney didn’t like the way Chase was mocking manager Frank Chance for the team’s amusement. He told Chance, and Chase was suddenly dealt to the White Sox.
