Peterborough Panthers booked their place in the Sky Sports Elite League play-offs after a stunning 51-39 victory at rivals Lakeside Hammers.
And now Lakeside’s place in the top-four is under serious threat as Coventry moved to within two points of them, with a meeting-in-hand, as they won at Belle Vue.
Lakeside have now ridden 31 league meetings which is the play-off cut-off points, so their meeting on Thursday against Swindon does not count towards their top-four position.
Peterborough’s success, though, was no fluke as they dominated from the off, and were never behind with captain Kenneth Bjerre leading the home with 14 points.
But arguably the real hero for the visitors was rookie Pole Krzysztof Buczkowski (5+2), whose second place in Heat 5, as he re-took Kauko Nieminen just before the line, was one of the rides of the season.
Niels Kristian Iversen (12+1), Rory Schlein (9+1) and Troy Batchelor (8+1) all performed very well grabbing at least a couple of race wins each, as Peterborough limited Lakeside to just four wins and two heat advantages all evening.
Lakeside number one Lee Richardson did his best with 11, but the likes of Nieminen, Adam Shields and Stuart Robson – all normally very reliable around Purfleet – failed to perform.
Lakeside’s defeat left the door open for Coventry and they took their chance with both hands as they romped to a 53-37 win at Kirkmanshulme Lane.
