Wigan pulled two points clear at the top of Engage Super League with an impressive 36-22 win that left Castleford still looking for a first home win of 2010.

The Warriors gave a debut to 22-year-old forward Chris Tuson, who was playing for third-tier club Blackpool Panthers a week ago, but it was the familiar figures of Pat Richards and Amos Roberts who laid the victory platform.

Richards, Super League's runaway leading scorer in the first seven rounds, took his points tally to 110 with a try and four goals, while Roberts claimed a hat-trick of tries to take his total to 10 for the season.

The Australian duo have scored 20 tries between them so far in Wigan's first seven matches but this was another superb all-round performance from Michael Maguire's men, who have rattled up 254 points so far.

In the day's other game Wakefield made amends for their last showing on home soil by demolishing Salford 36-6 in their clash at Hearwell Stadium.

The Wildcats were dismantled 52-0 by local rivals Huddersfield in their last home Super League outing.

But they were quickly out of the blocks on Sunday and 28 unanswered points in a brilliant first-half laid the platform for a deserved win.

Daryl Millard, Tevita Leo-Latu, Glenn Morrison, Dale Ferguson and Aaron Murphy all crossed in the first-half with Sam Obst, who starred in Danny Brough's notable absence, adding a try of his own and laying one on for Damien Blanch after the break.
