Team Context and Historical Significance

The Mariners enter the playoffs after finishing the 2025-26 regular season with a record of 42-21-6-3, accumulating 93 points – their best season in franchise history by point total. This performance likewise tied their all-time franchise wins record. The team’s playoff berth comes as the #2 seed in the North Division, setting up this first-round meeting with the #3 seeded Adirondack Thunder.

This series represents a rematch of the 2024 first-round playoff encounter between the two teams, adding familiarity to the rivalry. During the regular season, the Mariners and Thunder met 15 times – more than any other opponent pairing – with Portland holding a 5-5-3-2 record in those games. Notably, eight of those 15 contests required overtime or a shootout to determine a winner, highlighting the competitive nature of their matchups.

The Adirondack Thunder concluded their regular season with a 37-24-10-1 record. Both teams enter the series having experienced recent challenges, as Adirondack lost 10 of their final 13 regular-season games, even as the Mariners navigated their own late-season adjustments to secure their playoff positioning.

Fan Experience and Community Engagement

Beyond the on-ice action, the Mariners have organized several community-focused events to enhance the playoff atmosphere. The Pregame Block Party for Game 1 will feature live music from Down East Dead and interactive games including Port City Cornhole. These activities aim to create a festive environment in downtown Portland ahead of the puck drop.

The team’s affiliation with the Boston Bruins (NHL) and Providence Bruins (AHL) continues to provide developmental pathways for players, with several prospects seeing playoff action as part of their professional development. This connection adds another layer of significance to the series for fans following the Bruins’ organizational pipeline.

Looking Ahead

As the Mariners embark on this historic playoff run, the organization emphasizes the importance of sustaining momentum through the early games. Success in the opening two games at home could set a strong foundation for the series, while the team remains prepared for the potential extended battle that a best-of-seven format demands.
