Portland Sea Dogs

The Portland Sea Dogs are a Minor League Baseball team based in Portland, Maine, playing in the Eastern League. Established in 1994, the Sea Dogs are the Double-A affiliate of the Boston Red Sox.

The Sea Dogs became part of the Red Sox system for the 2003 season; previously they were affiliated with the Florida Marlins. The change in affiliation brought success in the 2005 and 2006 seasons as the Sea Dogs went to the Eastern League championship series both years. They won their first-ever title on September 17, 2006, defeating the Akron Aeros 8–5, in a rematch of the series from the previous year. It was the first Double-A championship for a Red Sox farm team since the New Britain Red Sox in 1983.
