Dubee, who turns 56 on Saturday, spent nine years in charge of the Phillies' staff before not having his contract renewed last month.
During his tenure, the Phillies boasted one of the better staffs in baseball, went to two World Series, won a title in 2008 and led the majors in ERA in 2011.
An aging and injured staff took a major step backward in 2013, when the Phillies finished 27th in the majors with a 4.32 ERA.
Dubee, a native of Brockton, Mass., lives in Sarasota, Fla., where the Orioles train. He has a relationship with Orioles executive vice president Dan Duquette that dates back to their days in Montreal when Duquette was general manager and Dubee was a minor league pitching coach.
The Orioles are expected to interview several candidates to replace Rick Adair, who will not be coming back in 2014.
