Cases Somerset Rebels will take a five-point lead to Scunthorpe Scorpions tomorrow for the deciding leg in the Premier League Grand Final.
The Rebels beat the Scorpions 49-44 in last night's first leg at the Oaktree Arena.
It was all level at 18-18 after six heats, but the home side struck their first major blow in the seventh heat when Kyle Newman and Claus Vissing combined for their first 5-1 of the night.
After another shared heat in the next outing, Jesper B Monberg and James Wright posted a 4-2 in heat nine, and then Craig Cook - replacing injured skipper Jason Doyle - and Alex Davies scored a maximum in the tenth.
That took the scores to 35-25 in the Rebels' favour, but their opponents wasted no time in using their tactical ride to optimum effect.
Josh Auty was handed the black and white helmet cover in heat 11, and he raced to victory with Scorpions team mate Anders Mellgren following him home - 8-1 to the visitors, and the overall score reduced to 36-33.
Somerset returned fire in heats 12 and 13.
Monberg and Lewis Kerr - in for the injured Tom Perry - gained a 4-2, before Vissing and Cook combined for a 5-1 to put the Rebels 45-36 ahead.
Ashley Birks and Michael Palm Toft made the start in heat 14 and clinched a 5-1 for the Scorpions over Wright and Newman, pegging the Rebels' advantage back to five points.
And that's how it stayed after a shared heat 15, won by Scunthorpe's Nick Morris but with Vissing in second and Monberg third.
The Premier League winners will be decided at Scunthorpe tomorrow afternoon (4pm).
