Wigan welcomed London to the DW Stadium but the Broncos did not make it easy as both sides played below expectations in a 18-8 victory for the Warriors.
An early penalty to the Broncos, gave them a chance to kick for goal and Kieran Dixon registered the first points of the game from the boot.
It took Wigan just under 10 minutes to move ahead.
Back-to-back-to-back sets for the Warriors left the Broncos defence staggered. Jake Shorrocks exploited one of these gaps and step through the line and slide under the posts.
London hit back straight from the kick-off as two errors by Wigan put the Broncos into good field position.
A grubber kick from Jordan Abdull behind the line was touched down by Jay Pitts who raced ahead of the labouring Shorrocks and Hardaker.
The decision was confirmed by the TMO, James Child, despite there being a suspicion of a knock-on.
Dixon converted to put London two points ahead once more.
As the half ticked by both sides were going blow for blow, both completing sets well with London being on the front foot in terms of territory.
HALF-TIME: Wigan Warriors 6-8 London Broncos
Wigan took seven minutes to retake the lead after a calamitous error from the Broncos.
Elliot Kear knocked on just five minutes out from his own line and Chris Hankinson was on hand to pick the ball up and take advantage.
The game laboured more so throughout the second half but with 55 minutes gone Wigan turned on the style.
Sean O’Loughlin and George Williams took advantage of the ragged Broncos line and Williams kicked the ball behind Dixon with Morgan Escare picking up and scoring under the posts.
With 15 minutes remaining, Broncos looked to get back into the game but Rhys Williams found himself held up over the line.
Time was ticking out for London but Dixon found himself with plenty of room on the right hand edge.
With just Hardaker to beat, Dixon passed inside to James Cunningham, but the hooker dropped the ball with the try line begging.
Wigan managed to hold on in the final 10 minutes but neither side played at their best in front of less than 5,000 at the DW Stadium.
