Wigan bounced back from their defeat to Warrington last weekend with a eight try hammering of Hull at the KC Stadium.
The Warriors threw down the gauntlet to their title rivals, who are in France to face Catalans this weekend, in an impressive showing.
Pat Richards was the star of the show, scoring a hat-trick of tries and kicking seven goals.
But it was the Wigan defence which will have pleased stand-in coach Shaun Wane, who took charge of the Super League leaders in the absence of head coach Michael Maguire, who is back home in Australia for personal reasons.
Richards opened the scoring after latching on to Paul Deacon‘s kick, and added a second try in the corner soon after, before Liam Farrell, Darrell Goulding and Sam Tomkins put Wigan out of sight at 22-0 at half time.
Tomkins added his second shortly after the break, and the young star cut loose in the second half, setting up Farrell for his own second with a brilliant inside ball, and Richards completed his hat-trick by getting on the end of a teasing kick by Tomkins.
Fourth placed Hull, on a high after their derby victory over Hull KR last time out, were left shell-shocked, and their top four berth now finds itself under threat by champions Leeds, who play Salford on Sunday.
