NOTES: Sea Dog scratches were Maxime Villemaire (right knee injury), Devon Oliver-Dares (broken collarbone), Grant West (flu), Spencer MacDonald (right bicep strain), and Ian Saab (suspended). Dylan McGuigan dressed for his first ever QMJHL playoff game in place of West, registering one shot on goal and three hits. Jordan Moore dressed for his second straight game in place of MacDonald, who took part in the team’s morning skate, but was not ready to play. Coyle’s eight goals are a new Sea Dog single series record.
Three Stars: 1. Gauthier (SJ) 2. Coyle (SJ) 3. Carrier (CB) Top Dog: Jurco
