WIGAN made hard work of seeing off lowly London Broncos at the DW Stadium.
Two tries from Tony Clubb and Dan Sarginson against their former side helped Wigan to come behind from an early deficit.
Iain Thornley also matched that tally, while Matty Bowen added the crowning glory with a long-range effort in the final minute.
But Wigan - who head to St Helens on Friday - had to weather a horrid opening which saw them go down 10-0.
Jamie O’Callaghan went over in the corner after two minutes and that was followed six minutes later by Mike McMeeken, who stepped inside Matt Bowen as Broncos dominated the early exchanges.
Warriors took 25 minutes to have a meaningful attempt at the London line and Blake Green’s high kick was held wonderfully by Joe Burgess. The 19 year old offloaded brilliantly to Clubb and the second rower darted over in the corner.
Wonderful play from Sarginson and Thornley helped Wigan go ahead 16-10 at the break.
After more good work by Green, Sarginson raced around Broncos wing Iliess Macani to bring the teams level and on the opposite side, three minutes before half-time, Thornley stepped inside three London defenders to score.
Joe Burgess and Bowen were the stand-outs for Warriors, with a slow second half lit up by some of their brilliant running, as they looked to increase the advantage.
Clubb grabbed his second of the game, bundling over from close range, with Williams adding the extras to make it 22-10 and stretch Wigan’s lead.
Sarginson grabbed his second nine minutes from time, latching on to Sam Powell’s cross field kick.
Broncos added a try with five minutes remaining, Iliess Macani scoring in the corner after good play from the away side, before Bowen’s final play.
