Portsmouth's Colby Bishop has now scored 10 goals this season
Colby Bishop's hat-trick helped Portsmouth to a crucial victory Norwich in an eight-goal thriller at Carrow Road.
Their second win in 17 Championship away games opens up a six-point gap to the relegation zone, while ending Norwich's play-off hopes.
Matt Ritchie and Regan Poole completed the rout, with Josh Sargent, Jack Stacey and Emiliano Marcondes scoring for the Canaries.
The home side are now 13 points adrift of sixth with three games to play.
Portsmouth took the lead on 15 minutes, Jordan Williams cut in on his left to whip in a deep cross, which Bishop met with an low, well-directed header.
But just six minutes later, Sargent restored parity for Norwich, smashing home after a corner was cleared into his path.
The tempo of the game was relentless, and Norwich almost went in front 10 minutes before half time. Kellen Fisher headed goalwards from Oscar Shwartau's cross, but Pompey keeper Nicolas Schmid saved with his feet.
Ritchie finished off a wonderful team goal for the visitors moments later as Josh Murphy reached the byline after a searching ball from Isaac Hayden, before crossing for the 35-year-old to tap home unmarked.
Bishop scored his second from a stoppage time penalty after Hayden was fouled in the box, and they picked up where they left off after the break.
Murphy shot from a tight angle before feeding the striker, who finished after George Long's initial save.
Stacey pulled one back for Norwich with a brilliant finish into the top corner after being fed by Jacob Wright's pinpoint through ball.
But Pompey restored their three-goal advantage through Poole's sweeping finish from Adil Aouchiche's cross.
Marcondes added Norwich's third late on but it was too late to avoid a fourth straight game without a win.
Post-match reaction
Norwich manager Johannes Hoff Thorup speaking to BBC Radio Norfolk:
"Based on the game, it is fair we didn't win it. There were many things defensively we didn't get right.
"It comes down to preparation and being ready for what your opponent brings to a game and we didn't match that at all.
"I had the feeling that every time they brought the ball forward it could be a chance or a goal against.
"We have to look at that; it is definitely a weakness. It is simple situations we struggle to deal with.
"I hate when you have to talk about desire in a football player but I think there was a difference in that today. Portsmouth had more at stake and was willing to throw their bodies in front of the ball.
"I don't think we matched them and that was one of the messages at half time. It seemed like the simple things were difficult today."
Portsmouth manager John Mousinho speaking to BBC Radio Solent:
"It hasn't quite sunk in yet. It was quite a stressful 90 minutes for me.
"Even at 5-2 up with eight minutes to go, I still didn't feel secure, probably because of the position we are in. I am delighted and once it sinks in, I'll be more pleased but we've got to go again tomorrow and make sure we are focussed again for Monday.
"We spoke before about putting it all together. We've done it in patches in games but not consistent enough. We do deserve to be in the Championship and we've mixed it with every team here.
"The next stage is making sure we do it more often."
