Lee Briers kicked a late drop-goal to give Warrington a shock win over Leeds in their Super League elimination play-off clash at Headingley Carnegie.
The Wolves skipper struck his second one-pointer of the match with 90 seconds remaining to give his side their first-ever play-off victory.
The Rhinos led 6-0 and 12-4 but failed to kill off the robust visitors.
Second-half tries by Michael Sullivan and Ben Westwood gave Warrington hope before Briers took centre stage.
The game was delayed by 10 minutes after the Warrington team were caught in traffic on their way to the game.
When the match finally got under way, Leeds took an early lead when Rob Burrow showed a neat turn of foot to go over.
Although Henry Fa'afili brought the Wolves back into it with a try in the right corner, the Rhinos went 12-4 when Burrow turned provider for Danny McGuire after 18 minutes.
Leeds skipper Kevin Sinfield added his second conversion, but the home side would have been further ahead had centre Clinton Toopi not dropped a pass with the line at his mercy.
Briers kicked a penalty on the stroke of half-time.
Then Sullivan made the deficit just two points with a second try within two minutes of the re-start.
Sinfield made it three from three with a penalty on 49 minutes after Toa Kohe-Love had been penalised for a high tackle on Ryan Bailey.
Sinfield landed a second penalty to extend his side's lead, but Warrington drew level just short of the hour when loose forward Ben Westwood dived onto a kick from Briers, who added the conversion.
Sinfield edged his side back in front on 67 minutes with a drop goal, but Briers replied in kind two minutes later to leave the scores deadlocked.
Then with extra time looming, Briers sent the Wolves fans into raptures with his second one-pointer of the night.
Warrington coach Paul Cullen
"Lee Briers dragged his team back into the game.He's the smartest, cleverest player in Super League bar none.
"We have been hardened by our season's adversity. We held our nerve and I thought that was evident tonight.
"We have played out an entire season in 80 minutes. It very much reflects our season. It was an honest effort and I'm proud of the way the club responded."
Leeds coach Tony Smith
"In the first half we pretty well dominated most areas but in the second half we played the game at the wrong end.
"They've got some opportunists in their team who came up with big plays.
"I thought we got out-wrestled tonight. They're playing different rules now. There were no penalties given in the ruck area. The only penalties were for high shots."
