Att: 66,281 Played at Old Trafford, Manchester
The Warriors were looking to join Bradford Bulls and St Helens as the only clubs in summer era in completing a League and cup double. Also it would be the last game in a Wigan shirt for Sam Tomkins, who is leaving in a world-record move to New Zealand Warriors. Pat Richards and Lee Mossop were also playing their last game for the Cherry and Whites.
On the other side was Warrington Wolves who were looking to go one better that last year and finally win the big prize. They also had Adrian Morley, Garreth Carvell and Mike Cooper playing their final game for the club.
After a cagey opening which saw Wigan stand-off Blake Green knocked unconscious from a punch by Ben Westwood after just two minutes, Richards gave his side the lead with a penalty goal.
Suddenly Warrington got some ball and hit the Warriors with a three try burst in an eight minutes spell. Joel Monaghan got things underway by out jumping Richards to juggle the ball down for the opening touchdown of the Grand Final.
Richards then put the re-start dead and the Wolves went straight back to the other end with Simon Grix taking Mickey Higham's short pass to cross for try number 2.
Westwood then made it 16-2 as he took Lee Briers pass to crash over the line as Stefan Ratchford kicked his second conversion.
Joel Monaghan then knocked himself unconscious attempting to tackle Richards and was carried off on a stretcher, the lengthy break gave Wigan time to regroup and they got back into the game just before the break when Darrell Goulding took Tomkins' pass to score the all important try.
At the start of the second half, the Warriors continued their comeback as hooker Michael McIlorum went over the line from dummy half.
And the comeback was complete on 52 minutes when Josh Charnley followed up Goulding's grubber kick to score his 43rd try of 2013.
Warrington then suffered another blow when Ratchford hobbled off and seemed to disrupt their attacking play as Wigan took control of the contest.
On 64 minutes, man-of-the-match Green scored the killer try which all but ended any hopes for the Wolves.
Over to Richards, who signed off in style by collecting a floating pass from skipper Sean O'Loughlin to score Wigan's fifth try and then he added the extras as the Warriors scored 28 unanswered points to claim their third Super League title.
