Hugo Leufvenius had the hat trick as the Sarnia Sting topped the London Knights 4-1 to improve to 19-4-1.
Sean Josling scored the eventual winner at 3:12 of the second period.
Sault Ste. Marie kept pace with a 4-3 win over Sudbury. That's the Greyhounds ninth win in a row so they're still one point back of front running Sarnia in the West Division.
The Sting are still the top ranked team in the country while the Sault moved up a spot and are ranked third behind the 19-5 Moose Jaw Warriors.
The Sarnia Sting play in Mississauga Friday night and travel to Erie Saturday to take on the Otters.
