Shane Byrne, Leon Haslam and Jason O'Halloran have become the first three riders to secure places in the MCE British Superbike Showdown, having collected a sufficient points margin over their rivals at Cadwell Park.
The trio made up the rostrum in both races at the Lincolnshire circuit with Byrne and Haslam sharing a win apiece while O'Halloran grabbed a third and a second.
The results, coupled with closest contenders outside the top six Showdown spots Richard Cooper and Luke Mossey in joint-seventh, sees the top three pull out over a 75-point margin. It means regardless of results at the Oulton Park triple-header in two weeks they will be part of the Showdown.
Byrne, who claimed his seventh race win of the year plus a third place, still leads the championship with 272 points while Haslam is within touching distance thanks to his fourth victory of the campaign in race two to move to 251 points.
With Cooper and Mossey tied on 133 points, O'Halloran's second place in race two saw him narrowly clinch the third spot as he holds a 78-point margin over the nearest contenders outside the key top six positions.
Heading to the final round before the Showdown comes into play, the final three spots will be decided between Michael Laverty, Dan Linfoot and James Ellison with Cooper, Mossey, Peter Hickman, Christian Iddon and Tommy Bridewell looking to displace those currently in the top six. Glenn Irwin and Lee Jackson still hold outside chances of a Showdown place but require huge points swings and those above them in the standings not scoring.
