With less than five minutes left, Evan Neugold skated in and lifted the puck top shelf to put the Panthers in front.
Middlebury increased its lead to 3-1 5:51 into the third when George Ordway showed persistence bringing the puck into the zone and scored unassisted from the slot during 4-on-4 play.
Alex Brenton put the Cardinals back within a goal a little more than two minutes later when he sped to the front of the net and redirected the puck past BonDurant.
Plattsburgh had a great chance a few minutes later, with Mark Constantine and Ryan Farnan coming down on a 2-on-1, but BonDurant turned away Farnan’s low shot from the right side. Docking later got open out front but only got a piece of the puck.
“We had some great looks (Friday),” Plattsburgh coach Bob Emery said. “We were not opportunistic at all. I thought in the third period alone we had three or four great chances to score, and we didn’t get the puck up. A couple open nets. And you don’t take advantage of that, you’re not going to win many hockey games.”
BonDurant finished with 23 saves for Middlebury. Cadieux had 18.
While Emery lamented the missed scoring chances, he was more unhappy with what went on in the other end.
“It’s the goals against that bother me. Two out of their three goals we did a very bad job in front of our net picking up sticks,” he said. “From a coaching standpoint, the mental mistakes are what you want to work on and kind of tick you off looking back at the loss.”
Tory Allan banged in Norwich’s first goal 5:50 into the second game. Norwich outshot Saint Thomas 16-4 in the second period. Shane Gorman tallied from out front 5:25 in, and the Cadets ended the period with a 2-0 lead.
