Sean Josling, with his fourteenth, rounded out the scoring for Sarnia in the final frame.
Sarnia associate coach Brad Staubitz liked what he saw on the ice.
"I thought we played a really good game. We generated a lot of offence, had good chances, even in the first period with odd man rushes, and Lamour played great in net for us."
Cameron Lamour made 37 saves for Sarnia while Guelph's Anthony Popovich and Nico Daws combined for 19 saves.
In a rarity the Sting claimed all "three star" selections with Lamour first star followed by Rees and Franco Sproviero who collected two assists.
