Swindon put themselves firmly in control of their KO Cup quarter-final after a 59-31 win over Rye House at the Abbey on Monday.
David Bellego and Troy Batchelor both scored four-ride paid maximums as the CFS Filtration Robins dominated on home shale, meaning they take a 28-point margin to Hoddesdon on Wednesday.
The Rockets were blown away in the first six races, during which time the rampant hosts carded three 5-1s and three 4-2s to open up a 27-9 advantage.
And although the visitors did manage a couple of later heat wins, they could do little to stem the overall tide.
Nick Morris and Adam Ellis gave the Robins a perfect start with a maximum over Chris Harris in Heat 1, and Batchelor and Bellego performed likewise in their two early outings together – Heat 3 seeing Krzysztof Kasprzak retire at the back.
Recent signing Jack Smith took important points off his direct rivals Emil Grondal and Max Clegg, and it took until Heat 7 for the Rockets to get a winner on the board as Kasprzak got the better of Tobiasz Musielak.
But the prolific Batchelor/Bellego combination carded their third 5-1 in Heat 9 with Bellego getting inside Scott Nicholls on the fourth bend – and Ellis then superbly chased and passed Edward Kennett in Heat 10, to complete a 5-1 with skipper Morris.
Musielak held off the charging Harris in Heat 11, which was the first of three successive shared races.
Heat 13 was stopped twice – firstly when Harris was sandwiched between Morris and Musielak and came down, forcing Nicholls to lay his machine down. The re-run produced a heavier crash, this time on turn four with Morris disqualified for his tangle with Nicholls which sent Harris into the fence at speed.
Musielak took the second re-run ahead of Nicholls and Harris, and another 5-1 from Bellego and Zach Wajtknecht in Heat 14 had the Robins close to the 60-point mark.
They were denied that landmark by Kasprzak’s Heat 15 win and mechanical trouble for Morris, but it had still been a thoroughly convincing show.
Boss Alun Rossiter said: “It was a good all-round team performance tonight. I said on the track walk that we shouldn’t take anything for granted, and really if we don’t make the semi-finals now we deserve a kicking.
“We’ve come off the back of the two losses, which were tough meetings and everybody wants to beat us, and we’ve hit back well after that.
“We had a good chat last week and put in a great performance against Wolverhampton, and now this was another very good one tonight.”
Robins will look to complete the job against the Rockets in Wednesday’s return, before turning their attention back to the Premiership and the visit of Jason Doyle-led Somerset on Bank Holiday Monday (7.30pm).
