A pair of controversial tries were not enough to save Manly from a rampaging Warriors attack as the visitors finished a horror 36-16 loss without injured stars Tom Trbojevic and Daly Cherry-Evans.
Jason Saab was the first to claim four contentious points as he dived over to score Manly's second try of the evening in the 46th minute.
The high-flying winger went over in the right corner and appeared to drop the ball on grounding, but was saved by the Bunker due to "inconclusive" evidence.
Warriors hooker Wayde Egan hit back moments later to extend his team's lead to 12 before Cherry-Evans was left nervously awaiting a review of his own efforts.
In a remarkable diving effort from Reuben Garrick, the winger partnered up with the Manly skipper to narrow the margin.
The pair capitalised on a break down the edge by Saab, who appeared to put too much power into his chip across the field but Garrick managed to get his hands on the ball and flick it back to Cherry-Evans before it went dead.
"Wow. That is a sensational play," Steve Roach said on Fox League.

"Look how hard those Manly players were chasing."
The sensational effort left Fox League's commentary team in awe, but a replay of the try appeared to show Garrick had stepped on the line.
"Oh, I don't know. I think his foot might be on the line," Roach continued.
"Is there a bit of chalk on that [boot]? I think he is on the line… but how good of a try would that have been?"
A lengthy review by the Bunker ultimately awarded a try, however.

Poor discipline then killed Manly's attack in the second half as Jake Trbojevic was given marching orders.
Roger Tuivasa-Sheck joined a chorus of teammates on the list of try scorers before Manly were left to cover the hole left by an injured Cherry-Evans and Trbojevic.
Cherry-Evans clutched at his back as he was assisted off the field by trainers just six minutes after Trbojevic headed down the tunnel.

It was unclear why Trbojevic had left the field but coach Anthony Seibold later confirmed it was due to "tightness" issues.
"Turbo was feeling a little bit of tightness… and Daly was having a bit of a spasm," Seibold said.
"I haven't spoken to the doctors yet but we will have to get them checked."
Luke Metcalf wrapped the match up in style for the Warriors as he dived over the line with seconds remaining on the clock.
