A final heat maximum from Peter Karlsson and Davey Watt gave Lakeside Hammers a 48-42 victory over Birmingham Brummies.
The Brummies took the meeting to a last-heat decider after they took their own maximum from Heat 14.
However, Karlsson and Watt were on hand to claim the win for Lakeside - although Birmingham did enough to take a point.
Lakeside were led home by Davey Watt with paid 14, whilst Lewis Bridger enjoyed one of his best night of the season with paid 11.
The evening's top scorer was the Elite League form man in the shape of Birmingham's Martin Smolinski with 12+1, whilst Jason Doyle - another in-form Brummie - scored 11.
One man who was way off form was Birmingham number one Chris Harris, who came home with a dismal paid 3.
