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 Eastern League title in 2006. 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 2011 Portland Sea Dogs included prospects Will Middlebrooks, Alex Hassan, Jeremy Hazelbaker, Oscar Tejeda, Alex Wilson, and Mitch Dening.

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