Springfield Thunderbirds Secure Historic Calder Cup Upset Over Providence Bruins
The Springfield Thunderbirds have etched their names into the American Hockey League (AHL) record books, completing what is statistically the largest upset in Calder Cup Playoff history. In a thrilling overtime finish on Thursday night, Springfield eliminated the Macgregor Kilpatrick Trophy-winning Providence Bruins, securing a 3-1 series victory and advancing to the Atlantic Division finals.
The magnitude of the victory is underscored by the regular-season standings; the Thunderbirds managed to take down a Bruins squad that had finished 38 points ahead of them in the standings, defying the odds in a dominant postseason performance.
The Game-Winning Moment
The deciding game remained a deadlock until 4:01 into overtime. The winning sequence began when defenseman Marc-André Gaudet intercepted an errant Bruins pass in the neutral zone at the Springfield blue line. Gaudet quickly transitioned the puck to Otto Stenberg on the left wing, sparking a three-on-two rush.
Stenberg found a seam to feed Chris Wagner, who then located Dillon Dube cutting toward the net. Dube beat Bruins goaltender Michael DiPietro to seal the 1-0 win. The goal marked Dube’s second goal and fifth point of the series, sending the Thunderbirds deeper into the postseason.
Defensive Mastery: The Romanov Factor
While the offense provided the final blow, the victory was built on the back of stellar goaltending. Georgi Romanov delivered a shutout in the final game, stopping 37 of 38 shots. Romanov’s performance throughout the four-game series was exceptional, posting a 1.47 goals-against average (GAA) and a .953 save percentage.
On the opposite side, Michael DiPietro stopped 27 shots in the final game, but the Bruins’ struggles in the postseason continue. Providence has now lost eight of their last nine playoff series since their appearance in the Eastern Conference Finals in 2017.
Fresh Talent and Next Steps
The series also served as a launching pad for the next generation of talent. Two of the St. Louis Blues’ most recent first-round draft picks—defenseman Adam Jiříček (16th overall in 2024) and forward Justin Carbonneau (19th overall in 2025)—both made their AHL debuts for the Thunderbirds during the game.
With the series win, the Thunderbirds now shift their focus to the Atlantic Division finals, where they are scheduled to face Wilkes-Barre/Scranton.
