Sheffield Steeldogs went in to their fourth playoff game knowing they needed a minor miracle to progress – but were beaten by a Peterborough team with more realistic ambitions.
After a sluggish start to the game, Arnoldas Bosas skated down the left wing and went backhand to put the Steeldogs in front at 4:07.
The Phantoms became increasingly influential and after some near misses, James Ferrara squeezed a shot under Hadfield's pads and then Will Weldon gave them the lead with a top shelf finish.
The Dogs made a positive start to the middle period and a determined Donatas Kumeliauskas scored after he'd already been knocked off his feet.
Ex-Steeldog Edgars Bebris bundled the puck in to the net to give the visitors a 3-2 advantage which Levers should have increased but he fanned on the puck with Hadfield stranded. Stanislav Lascek hit the crossbar and the Phantoms broke back and Robson notched number 4 just before the half way mark.
The final period got off to a quick start and it was Pliskauskas who made the clinical finish on a breakaway to kill off the Dogs.
Petr Stepanek who had tormented them in the previous game added Peterborough's sixth, spinning to fire a shot in off the post.
A 6-2 loss means the Steeldogs will just be playing for pride in their final home on Friday (7:30) against the Guildford Flames.
