The visitors struck first on the power play as Pierce Mbuyi was left alone in front of Petes goaltender Zach Bowen after a pass from Antonio Tersigni. Mbuyi beat Bowen short side and made it 1-0 after one.
Owen Sound found themselves with another man advantage and Mbuyi struck again. This time, he wristed a shot from the point that found its way through traffic and the back of the net for a 2-0 lead.
The Petes had an opportunity to get back in the game with a five-minute power play due to a James Petrovski cross check from the Attack. Peterborough turned the puck over in the attacking zone thanks to Braydon McCallum and fed Johnathan Melee for a one-timer and power play goal. The Petes trail 2-1 heading into the third.
Both teams struggled to score in the third until late in the frame where Ben Cormier got a pass and one-timed it home past Bowen for a 3-1 lead late in the frame. Peterborough pulled their goalie to try and get back in the game but after LA Kings prospect and Owen Sound goaltender Carter George made a save he took a shot at the empty net. He potted the goalie goal to make it 4-1 for the dagger.
The Petes hit the road to take on the Kitchener Rangers on Friday at the Kitchener Memorial Auditorium, with puck drop scheduled for 7 p.m.
