Trevor Swales' men secured their top-flight safety with a crushing club record success over weakened Wolverhampton that came complete with what is thought to be a Peterborough first – both reserve riders helping themselves to paid maximums in the same meeting.

Panthers were hot favourites to dodge the trapdoor after a smashing comeback in the first leg at Monmore Green on Tuesday when they only went down by a point.

And that soon became reality as they performed like odds-on certainties with bottom-end men Claus Vissing and Karol Zabik astonishingly being paid for 30 points between them.

Panthers didn't just finish the job back on their home shale – this was far more explosive than that. The city slickers ruthlessly tore apart rock-bottom opposition that looked every bit the worst team in the Elite League.

Massacring the men from the Midlands is becoming something of a tradition in these parts as Panthers bettered their 66-24 drubbing of the same opponents late in 2007 with this even more emphatic rampage.

The visiting Wolves were nothing but lambs to the slaughter as the city side brought the curtain down with a sizzling series of six 5-1s on a night when they claimed no fewer than 10 maximums in total.

"To get a paid maximum is a brilliant feeling and I wish the season was not about to end," admitted Zabik after underlining his new-found status as a club hero.

"We knew we had to race hard and that is what we did to make sure we won and gave our fans something to celebrate. And now I hope they can't wait for next year to start, just like me."

But the joy of bagging a biggest-ever victory in their final competitive outing of the campaign was tempered by nasty injuries to riders in both teams.

Stand-in Panthers skipper Danny King was taken to hospital with a fractured foot after an awkward three-man accident after only a few metres of heat 11 (Read more: Injured skipper King fuming after crash).

King and Wolves pair Fredrik Lindgren and Morten Risager all came down in a heap – the Panthers rider bearing the brunt of the impact and then insisting the blame must lie with Lindgren.

The tangle left Risager nursing a hand injury that left him unable to take any further part, while Lindgren did complete the meeting but managed only one further point from three remaining rides.

Cursed captain King had earlier been unfortunate to be involved in the other major flashpoint of a long night when he was caught up in a frightening heat seven smash that left former Panthers title hero Niels Kristian nursing a dislocated shoulder for the third time this season.

But the Danish racer can count himself seriously lucky to have suffered nothing more serious after his attempts to roar around the outside of race leader Zabik on the second bend of the final lap ended in tears.

Iversen clipped the fence, high-sided and tumbled into the path of the following King and despite taking evasive action, the Panthers man could not miss the Dane's machine and came down heavily. The meeting ceased to be a contest after Iversen's exit with wilting Wolverhampton (who were already without ill David Howe) only able to provide three heat winners all night.

One of those, Panthers asset Jesper B. Monberg, summed up the visitors plight. He admitted: "The fact I was our top scorer with seven points shows what a bad night it was for us.

"It was always going to be tough to get a result here and it became even harder when we lost Niels.

"He is one of our top riders and always goes well at Peterborough, but I have to admit that Panthers were very, very good."

And Monberg was powerless to stop guest star Rory Schlein putting the icing onto the Panthers cake in the finale.

The hosts needed a 5-1 to post a new entry into the record books and that's exactly what they got when Schlein went round the outside of Monberg to follow home partner Kenneth Bjerre.

Now the prospect of facing Premier League play-off victors King's Lynn or Edinburgh must really fill Wolves with trepidation. However, with their officials already insisting in the speedway media that they will be operating in the top-flight next season, one can only hope the past 30 heats haven't been an expensive and sometimes painful waste of time.
