Dufty was signed by New York Red Bulls on 12 March 2009, and made his MLS debut on 11 April 2009, as a substitute for Danny Cepero in the eighth minute of a Major League Soccer match against Houston Dynamo at Robertson Stadium. Dufty did not concede a goal as New York held Houston to a scoreless draw. However, despite a strong display, he was waived by the club only three days later.
