Ducey was part of a Major League anomaly in 2000, when he was traded by the Phillies to the Blue Jays on July 26 for John Sneed, and was then traded by the Blue Jays back to the Phillies on August 7 for Mickey Morandini.
Ducey spent one year each in the New York Yankees' and Montreal Expos organizations as a minor league hitting coach, before he was hired in 2006 by the Blue Jays as a scout. He began covering both the major and minor leagues, as well as spring training before moving to the Pacific Rim department. He was fired by then-new general manager Alex Anthopoulos in October 2009 when coverage of Asia was not a priority for the Jays. He was hired to scout for the Tampa Bay Rays in the 2011 season, then joined the Philadelphia Phillies minor league system in 2014, again serving as a hitting coach.
He is married to Yanitza, with whom he has two sons, Thomas and Aaron, and one daughter, Jenaka.
