Home of the Maine Monster
The longtime home of the Portland Sea Dogs underwent a name change in 2024 when local medical insurance company Delta Dental entered into a multi-year naming rights agreement with the team. However, you’d be hard pressed to find anyone that uses the facility’s formal name. To almost everyone around, the home of Maine’s favorite ball team continues to be Hadlock Field. The ballpark is named for longtime Portland High School baseball coach and physics teacher Edson J. Hadlock Jr. The Sea Dogs began competing in the AA Eastern League in 1994 as the Florida Marlins’ affiliate. In 2003 the Sea Dogs switched affiliations to the nearby Boston Red Sox, which only strengthened the bonds between the city and team.
When the city of Portland was awarded an Eastern League expansion team in 1992, the city renovated Hadlock Field, which was being used at the time as a high school field. To this day, Hadlock Field is used by both the Portland High and Deering High School baseball teams.
Over their existence, the Sea Dogs have won one Eastern League title along with six division titles. The Red Sox-Sea Dogs affiliation shows no signs of slowing down, as the clubs are currently contracted to be affiliated through the 2030 season.
Food & Beverage 4
At first glance, it wouldn’t seem like Hadlock Field would offer much more than a traditional concessions experience. Most of the stands, tucked away under the grandstand, have a real old-school feel to them. But a closer look shows a decent variety of food available and some local treasures hidden within the old menu boards of Hadlock Field.
The main stands offer standard ballpark fare. In between the Fenway Franks, burgers, pizza slices, chicken tenders and the like are more unique items, such as full-sized batting helmets filled with french fries, buffalo chicken subs, and steak and cheese subs. A few uniquely Maine items are worth checking out: Red Snapper hot dogs and of course, lobster rolls.
Be sure to bring your sweet tooth to a Sea Dogs game, as in addition to the usual fried dough, candy and ice cream are two local “must have” items. First is the Whoopie Pie, which is so ubiquitous to Maine that it is used as one of the team’s alternate identities. The other may be the most popular concession item at Hadlock Field, the Sea Dog biscuit. The biscuit is two chocolate chip cookies with a scoop of Gifford’s vanilla ice cream in between.
Coca-Cola products are featured at Hadlock Field. As you would expect in a craft brewing hotspot like Portland, the microbrew game is impressive here. Local brews from Allegash, Geary’s, Sea Dog, Baxter, Red Hook, Shipyard, Harpoon, Sebego and Sam Adams can all be found at the microbrewery stand on the first base side of the stadium.
Atmosphere 4
While Hadlock Field’s physical constraints limit what Sea Dog staff are able to do in many regards, the staff here pack every game with plenty of activity, distraction and noise designed to keep the younger and casual fans in attendance engaged and entertained. Theme nights and giveaways fill the schedule, and activities between every half inning take place on the field, meaning that whether you are visiting Portland for the baseball action or not, you will leave entertained.
A statue of the Sea Dogs’ mascot, Slugger the seal greets fans at the entrance to Hadlock Field. This is a popular spot to meet before or after the game and to pose for a picture. The actual Slugger, a member of the Mascot Hall of Fame, is one of the more entertaining mascots in the minor leagues and is integral to the gameday presentation. Unique to Hadlock Field are the “Trash Monsters,” mascots who also serve as trash cans. Young fans line up to throw out their garbage into the mouths of the “monstahs” throughout the game. It can’t be fun to be the poor intern in that costume during the hot summer months.
Anyone who has spent any time in Red Sox Nation can testify how dedicated and intense fans are in this part of the country. The Sea Dogs’ affiliation with the Red Sox guarantees that the fans in Portland know the players well and are invested in their success. Unfortunately, Sea Dog fans share some bad habits with their parent fans in Boston, in that they are always in motion, blocking views and distracting fans from the action going on down on the field.
Neighborhood 4
The city of Portland is often mentioned among the top destinations in all of minor league baseball. The city features a thriving arts scene and is a favorite amongst foodies. In particular, if you love seafood, you won’t find a city with a greater diversity and quality of restaurants than Portland. In addition, Portland has an active craft beer scene, with several fine breweries located in the immediate area. Shoppers will flock to nearby outlet malls in Kittery, just to the south of the city, or Freeport, just to the north. What keeps Hadlock Field from receiving a perfect score in this category is that it is located away from the city center near I-295. Most of the city’s attractions are a short drive away.
For the best of what Portland has to offer, head down to the Old Port neighborhood. This historic district, known for its cobblestone streets, 19th-century brick buildings and fishing piers, is the tourist, culinary and cultural hub of the city. Some of the best seafood you’ll ever have is found in the Old Port, as food is practically taken right from the ocean and put on your plate. The boutiques, shops and bars that line the crooked, hilly streets and docks of the Old Port make this one of Maine’s top tourist destinations.
Maine dubs itself “Vacationland,” and whether your idea of relaxing involves a sandy beach, an amusement park, a museum, a day on the bay or hiking through the woods, you’ll find what you need in and around Portland. Check out VisitMaine.com for more details.
Fans 4
Even after two decades as the Red Sox AA Eastern League affiliate, the Sea Dogs continue to pack fans into Hadlock Field. In 2025 the team attracted over 5,800 fans per game, good for fourth in the league rankings.
The team’s affiliation with the nearby Boston Red Sox (Fenway Park is 107 miles away) ensures that the fans in Maine are knowledgeable about the team and passionate about the action taking place down on the field. It’s a shame that more of them don’t sit down and watch the game for a while.
Access 4
Hadlock Field is easy to get to, located just a few blocks from Interstate 295. Simply take the Congress Street exit and follow the signs to the ballpark. Parking is available in surface lots around the ballpark, including at the adjacent Fitzpatrick Stadium. On-street parking is also available but pay attention to signs for hours and restrictions.
Fans will enter Hadlock Field onto a concourse that stretches underneath the length of the seating bowl. The small but well-stocked team store will be immediately to your left, with concession stands lining the wall in front of you. The concourse can get crowded when the park is filled, but generally fans should have no issues getting around. Rest rooms are located on either side of the ballpark and are plenty big enough for a typical Sea Dog crowd.
Due to the presence of the Portland Expo Center next to Hadlock Field, the seating bowl of the ballpark is irregular, running from about first base around to deep left field. Most of the seating consists of green folding plastic stadium seats, with some metal bleachers along the top of the seating bowl and in deep left field. An inner walkway runs along the length of the seating bowl, separating the box seats from the reserved and general admission seating.
Return on Investment 4
Tickets to Sea Dog games range in price from $15-$29. Children, seniors and members of the military receive a $1-$3 discount depending on the type of ticket purchased. Waiting until gameday to buy your tickets will add a two-dollar surcharge to them. For an extra three dollars, fans can purchase Assurance tickets, which allows for transfer of tickets to another home game should plans change.
Parking in the many lots around Hadlock Field costs between ten and twenty dollars. Unfortunately, the ample free on-street parking that could be found around the ballpark is not available on most nights. Pay attention to parking signs in the area if looking for on-street parking.
Extras 5
The Sea Dogs have a staggering number of alternate identities to honor local foods and notable Maine things. Of course, each identity comes with its own amazing set of gear. Check out the team store or site for your Whoopie Pie, Bean Suppah, Red Snappah, Lobstah Bake, and Candlepin swag.
Hadlock Field is loaded with touches designed to evoke memories of the ballpark’s Maine location. Keep a look out for the lighthouse hidden beyond the centerfield fence which rises after every Sea Dog home run and victory.
Hadlock Field has many features meant to mimic their parent club’s ballpark in Boston. In left field stands a 37-foot-tall replica of Fenway’s Green Monster, known here as the Maine Monster. Hadlock has its own version of Fenway’s Monster Seats, located high above the right field wall over the Sea Dogs bullpen.
Located on the concourse is every Sea Dog team and award winner since the franchise’s inception in 1994, as well as the Sea Dog Hall of Fame. There is also a display listing every Sea Dog alumnus to make the major leagues. Each season, every Sea Dog alumnus to play for the Red Sox has his jersey displayed on the façade of the press box.
Every season, the Sea Dogs end their season with their “Field of Dreams” game, in which the players emerge from a corn field in center field to play their finale.
Final Thoughts
Hadlock Field is often named among the top minor league ballparks in the nation. This may have more to do with where it is rather than what it is. Hadlock may not be the most modern minor league ballpark, but it is filled with enthusiastic, knowledgeable fans and plenty of kitschy touches. A day spent at Hadlock Field and the Old Port is one of the top Stadium Journeys you’ll ever experience!
