Wolves through to Grand Final
Warrington are 80 minutes away from the double after winning 36-18 at St Helens to book a first Grand Final appearance, where they face Leeds.
Two tries in a three-minute spell midway through the second half from Australian forward Trent Waterhouse clinched victory for the Wolves, who will meet the Rhinos at Old Trafford next Saturday in a repeat of last month's Challenge Cup final which they won 35-18.
Warrington, who will become only the sixth club to contest the Grand Final, ran in four second-half tries to thwart Saints' bid for a seventh successive trip to Old Trafford and bring Mike Rush's reign as caretaker coach to a sorry end.
St Helens, the last team to do the double in 2006, dominated the first half and ought to have been further ahead than 14-12 at the break but they quickly ran out of steam when Warrington got their second wind in the second half.
The Wolves, who lost to Saints in the opening round of the play-offs, were boosted by the return of Man of Steel contender Ben Westwood for his first appearance since Wembley but it was his second row partner Waterhouse who stole the show.
The former Kangaroo international was a Grand Final winner in the NRL with Penrith Panthers back in 2003 and will fancy his chances of doing the double.
Yet Saints had looked the more dangerous side throughout the first half with right winger Tommy Makinson going close and left winger Francis Meli denied by a forward pass from Jon Wilkin and it was no surprise when they opening the scoring on 11 minutes.
Makinson had no right to score after taking Chris Flannery's pass with Chris Riley still to beat but he produced an acrobatic dive to get around his man and plant the ball over the line.
It was against the run of play that Warrington took the lead on 17 minutes, with Wilkin conceding possession with a knock-on 30 metres from his own line and Richie Myler combining with Brett Hodgson to get Riley over at the corner.
Hodgson's touchline conversion made it 6-4 but Saints remained unfazed and they looked to have seized control with two tries in a 10-minute spell.
Second rower Mark Flanagan took the ball to the Warrington line of defenders to suck in their defence and his long, looping pass gave Meli the space to cross at the corner.
The big Kiwi would have had a second try but for a last-ditch tackle from Hodgson but the Warrington full-back blotted his copybook shortly afterwards, spilling Wilkin's towering kick to present his opposite number Paul Wellens with the easiest of scores.
Makinson kicked his first conversion at the third attempt to make it 14-6 but Warrington scored what proved to be a crucial try two minutes before the interval when loose forward Simon Grix charged onto Lee Briers' pass.
The visitors were back in front eight minutes into the second half when right winger Joel Monaghan was first to Briers' high kick and, although he dropped the ball, it went backwards and he had the presence of mind to gather it back up and touch down.
Hodgson maintained his accuracy with his third goal to make it 18-14 and the Wolves produced some tremendous defence to keep their lead intact before hitting a purple patch in which they ran in three tries in seven minutes.
The impressive Waterhouse supported a break by centre Ryan Atkins to score his first before powering through a tiring defence for his second while Riley finished off a smart crossfield passing move to claim the visitors' sixth try.
Meli stopped the rot with a consolation try eight minutes from the end but Hodgson wrapped up the scoring with a penalty to take his goal tally to six from seven attempts.
