The Portland Sea Dogs are a minor league baseball team based in Portland, Maine, that currently plays in the Eastern League as part of the Eastern Division. 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 1983 when they were based in New Britain, Connecticut.
The Sea Dogs' home stadium is Hadlock Field, named after long-time Portland High School baseball coach Edison Hadlock. It currently has a seating capacity of 7,368. Hadlock Field is often visited by vacationing celebrities, such as former NFL coach Bill Parcells, former U.S. President George H. W. Bush, and his wife Barbara. 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. Along the right-field foul line just beyond first base, a picnic pavilion is available for group outings from 20 up to 300 people. In 2006, a new pavilion opened above the right-field wall over the Sea Dogs bullpen. Modeled after the Green Monster seats at Fenway Park in Boston, it seats up to 393 people and gives fans an opportunity to catch a home run ball. Currently all games are carried on a network of radio stations with Mike Antonellis providing the play-by-play, with the flagship WPEI and select TV games on NESN with Eric Frede play-by-play and former Red Sox relief pitcher Ken Ryan.
Sea Dogs games are frequented by the team's official mascot Slugger the Sea Dog.
Portland Sea Dogs Wikipedia
Minor league baseball officially returned to Maine on October 4, 1992, when Portland was awarded one of two Eastern League expansion franchises (the other being the New Haven Ravens) to begin play in April 1994. The Sea Dogs signed an affiliation agreement with the Florida Marlins on May 3, 1993, beginning what would become a nine-season relationship. The city renovated Hadlock Field, transforming what was once a high-school stadium into a professional ballpark.
City manager Robert Ganley led efforts to renovate Hadlock Field and return professional baseball to Portland.
The team won its first game, defeating the Reading Phillies on the road 2–1, with the help of a 14th-inning home run by future major league catcher Charles Johnson. The team opened Hadlock Field on April 18, 1994, losing 7–6 to the Albany-Colonie Yankees.
Cartoonist Guy Gilchrist designed the team's logo as well as logos for the Connecticut Defenders, Binghamton Mets, and New Britain Rock Cats. Gilchrist's comic strip Mudpie had a series of strips in which the young cat's family visit the Portland area and attend a Sea Dog game.
