The Petes were thumped 7-2 by the rival Kingston Frontenacs in-front of a sold out crowd at the Peterborough Memorial Centre.
Five Petes players made their OHL debut at the PMC Thursday night, including Colin Fitzgerald, Blake Gown, Genc Ula, Adam Levac and Francis Parish.
Gowan picked up a point in the loss, assisting on Chase Lefebvre’s first goal of the season which broke the Fronts shutout in the second period.
The Petes would score a second time to cut the Kingston lead to 3-2 in the second period on a tally by Caden Taylor, but that was as close as they would come.
The Frontenacs put two more behind Zach Bowen before the end of the second period to go up 5-2.
Kingston would add two more goals in the third period to take the game 7-2.
The Petes are back in-action tonight, up north in North Bay to play the Battalion at 7 p.m.
