Former Wests Tigers full-back Brett Hodgson's accuracy with the boot proved vital as Warrington Wolves saw off a spirited second half comeback from Super League leaders Wigan Warriors to win a pulsating clash 22-12 on Monday.
The home side had stormed into a 10-0 half-time lead with Ben Westwood scoring early on and Hodgson adding the extras, before centre Joel Monaghan plunged to touch down a neat Lee Briers grubber kick in the corner shortly before the break.
But Wigan stormed back after the interval with Sam Tonkins stretching for the line before Cook Islands international wing Anthony Gelling also dived over for a try.
Pat Richards converted both to give Wigan a 10-12 lead as the visitors dominated proceedings, but with five minutes left on the clock the ball was spun wide to Chris Riley whose chip ahead evaded the chasing pack and bounced perfectly for hooker Micky Higham to score his fifth try of the season for Warrington.
Late on Chris Hill burst through to score with Hodgson making short work of the extras to end Wigan's 11-game Super League winning streak and reduce the gap between the two teams at the top of the table to just four points.
