Dan Linfoot extended his championship lead after beating rivals Richard Kerr and Alastair Seeley to the first National Superstock race win of the weekend.
In a dramatic last lap, the Optimum Bikes Racing Ltd rider sized up leader Seeley and when the SYNETIQ BMW rider ran slightly wide at Druids after a tiny mistake, Linfoot seized his chance to sweep through into the lead.
Behind, Richard Kerr also found a way past Seeley at Lodge on the final lap to steal second place. Seeley had to make do with third place ahead of Joe Talbot, as Lewis Rollo finished in fifth position.
