Warrington Wolves opened up a two-point gap at the Super League summit by thumping Wigan Warriors 40-10 at the Halliwell Jones Stadium, proving their credentials as potential champions.
The two sides went into Thursday's clash level on 18 points, with just second-placed Catalans Dragons between them, but a dominant display from Warrington against opponents depleted by injuries saw them move clear.
The Wolves mounted much of the early pressure, but had tries by Ashton Sims and Stefan Ratchford ruled out before Josh Charnley slid over in the corner to put Wigan ahead.
An impressive dummy enabled Daryl Clark to cross before Ben Westwood crashed within a minute of replacing Sims, and Warrington did not surrender their advantage from then.
Kevin Penny made it 18-4 before the break when he leapt to claim and touch down a kick from Kurt Gidley - the Australian adding 10 points with the boot in his first outing since signing a new contract with the club.
A double from Ryan Atkins in the second half extended Warrington's lead and Benjamin Jullien then got in on the act, touching down his first try for the club.
John Bateman pulled one back for Wigan, but Westwood powered over for his second of the night to inflict a heavy defeat on Shaun Wane's side in his 150th match as head coach.
The only sour note for Warrington was the withdrawal of Tom Lineham after 12 minutes following a heavy hit from Tony Clubb.
