Springfield's stunning run shakes up the Calder Cup playoff bracket

Springfield did more than win a series. The Thunderbirds knocked out Providence, then watched Colorado keep rolling, and suddenly the Calder Cup bracket looked nothing like the regular season suggested. With the field down to the league’s divisional finalists, Springfield, Wilkes-Barre/Scranton, Toronto, Cleveland, Chicago, Grand Rapids, Colorado and Coachella Valley were still standing, while top-five regular-season finishers Providence, Ontario and Charlotte were already out.

The biggest bracket shift came from Springfield’s takedown of Providence, the clearest upset in the playoffs and the one that changed the way every remaining team had to view the road ahead. Providence had taken the Macgregor Kilpatrick Trophy with a 54-14-2-0 record and 110 points under Ryan Mougenel, and Michael DiPietro had been voted the league’s most valuable player. Springfield finished 38 points behind the Bruins, the largest margin ever overcome in a playoff series, yet still pushed Providence out of the tournament. That kind of result does more than eliminate a favorite. It tells every survivor that point totals and seed lines can disappear the moment the game tightens.

Springfield’s earlier escape from Charlotte made the run even louder. After opening that series with an 8-1 loss, the Thunderbirds became the first team in Calder Cup Playoff history to win a series after losing Game 1 by more than five goals. They then scored six of the final seven goals against the Checkers, a turnaround that turned one bad night into a warning for the rest of the bracket. For whoever drew Springfield next, the matchup no longer looked like a favorable path around a lower seed. It looked like a team that had already survived the worst kind of pressure twice.

Colorado emerged as the other club that changed the bracket’s shape. Trent Miner recorded his third shutout of the 2026 postseason in Game 3 against Henderson, then finished the job as the Eagles eliminated the Silver Knights in four games with a 6-2 win to advance to the Pacific Division finals for the third time in five years. Miner went 4-1, posted a 0.94 goals-against average and a .960 save percentage, and became the first AHL goaltender since Rochester’s Mika Noronen in 2000 to start a postseason with three shutouts in five games. That kind of goaltending makes Colorado a matchup problem, especially for teams hoping to win by tempo and volume.

The surviving favorites no longer had the comfort of clean seeding logic. Springfield’s run stripped away the regular-season order; Colorado’s control showed how quickly a series can tilt when one team owns the crease. The final eight had become a test of who could handle volatility, not who had looked best in April.
