Wigan pulled two points clear at the top of Engage Super League with an impressive seven-try 36-22 victory 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 on Sunday.

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.

Wakefield made amends for their last showing on home soil by demolishing Salford 36-6 in their clash at the 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 here 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.

Huddersfield Giants winger Leroy Cudjoe ran in a hat-trick of tries in a 32-18 victory at Harlequins on Saturday.

Lee Gilmour and Cudjoe bagged tries inside the first six minutes as the Giants opened up an early 10-0 lead.

Despite Cudjoe's second score, Chad Randall's try then helped Harlequins haul it back to 14-6 by the interval.

But Cudjoe struck again after the break and, despite Quins' late rally, Eorl Crabtree and Stephen Wild settled it.

Gareth Thomas was helped off injured as he was given a tough rugby league baptism on a wet night as his Crusaders side beat Catalans Dragons 14-6 on Friday night.

The Wales rugby union legend was just half-an-hour into his engage Super League debut when he was hurt in a heavy tackle and forced to leave the field.

Until then the 35-year-old had barely made an impact in a dull encounter at the Racecourse Ground, but the Welsh side ultimately prevailed after tries from Jason Chan and Peter Lupton.

Initial word suggested Thomas, who had struggled to his feet and attempted to play the ball after the tackle, had suffered concussion but, although he did not return, he was not seriously injured.

The anticipated first appearance of Thomas, signed from Cardiff Blues earlier this month, contributed to a healthy crowd of 6,124 - more than double the figure that watched last season's corresponding fixture in Bridgend.

Elsewhere on Friday night, Hull KR recorded their first league win at Headingley for 25 years as Leeds' miserable start to the season continued with a 17-10 defeat.

Liam Colbon, Peter Fox and Shaun Briscoe gave the East Yorkshire side a 16-6 lead at the interval.

Although Leeds, who have now lost four of their seven fixtures this season, managed to reduce the deficit to six points with a score from Keith Senior, the Robins held on for a memorable win.

The accurate boot of 20-year-old Kyle Eastmond denied Warrington the chance to end their Knowsley Road hoodoo as St Helens secured a 28-18 win.

With both sides scoring four tries, the outcome hinged on the goalkicking of half-back Eastmond, who kicked six goals from six attempts, including two touchline conversions, and also scored a delightful solo try to underline his growing importance to Saints.

Mick Potter's men, who were at full strength for the first time this year, were cruising to a fifth win when they led 20-4 after 52 minutes but the Wolves ran in three tries in eight minutes to set up a grandstand finish.

But Ade Gardner's second try on 65 minutes ended the fightback, condemning the visitors to only their second defeat of the season.

An outstanding performance from veteran Australian forward Craig Fitzgibbon proved to be the difference for Hull as they maintained their 100 per cent home record with a gritty 18-6 win over Bradford.

Two tries from Jordan Tansey and one from Lee Radford secured the points for Richard Agar's men on paper, but on a wet and miserable night, it was the sheer determination and endeavour of Fitzgibbon that dragged the home side over the line.

Bradford were hamstrung by the late withdrawal of playmaker Matt Orford through illness and short of Paul Sykes' first-half penalty and Stuart Reardon's late consolation, they offered little in attack as they slipped to a fourth loss of the season.
