Delta Dental Park at Hadlock Field is a minor league baseball stadium in Portland, Maine.
Hadlock Field is located between Interstate 295, the historic Fitzpatrick Stadium, and the Portland Exposition Building, the second-oldest arena in continuous operation in the United States.
In 2003, when the Sea Dogs affiliated with the Boston Red Sox, various features were added to the stadium to allude to Fenway Park: a replica Green Monster, called the Maine Monster, in left field;[4] a replica Citgo sign; and a large Coke bottle.
[7][8] In April 2018, Hadlock was named one of the ten best Minor League Baseball (MiLB) stadiums.
[10] When a Sea Dogs player hits a home run, or when the team wins, a fog horn sounds and a light house emerges from behind the outfield fence.
[11] In 2024, Maine lawmakers granted the Sea Dogs $2 million in tax breaks for a new player clubhouse and to make renovations to the playing field.
