The Portland Sea Dogs are the Double-A minor league affiliate of the Boston Red Sox. Established in 1994 and based in Portland, Maine, the Sea Dogs play in the Northern Division of the Eastern League. 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 title on September 17, 2006, defeating the Akron Aeros 8-5 in a rematch of the championship series from the previous year. It was the first double-A championship for a Red Sox farm team since 1983 when they were based in New Britain, Connecticut. The Portland Sea Dogs play their homes games at Hadlock Field, named after long-time Portland High School baseball coach Edison Hadlock. It has a seating capacity of 7,368. In left field stands the Maine Monster, a 37-foot-tall replica of Fenway Park's Green Monster, complete with Coke bottle and Citgo sign.

The 2010 Portland Sea Dogs include prospects Luis Exposito, Che-Hsuan Lin, Casey Kelly, Jose Iglesias, Stephen Fife, Chih-Hsien Chiang, Anthony Rizzo, Yamaico Navarro, Nate Spears, and Félix Doubront.

Although not much of a prospect, the Sea Dogs' loveable mascot Slugger the Sea Dog is every bit a part of the team.
