Craig Hall and Kirk Yeaman each scored twice as Hull maintained their 100 per cent engage Super League start by beating Bradford 36-24.

The visitors ran in six tries at the Grattan Stadium to notch up their fifth win of the season and leave the Bulls still looking for their first after four outings.

Richard Horne, in fine form after an injury-ravaged 2008, also got on the scoresheet along with Chris Thorman while Danny Tickle booted six goals to take his season's tally to 23.

Yet despite dominating, Hull could not quite kill off the game and Bradford kept the scoreline respectable with tries from Ben Jeffries, Rikki Sheriffe, Semi Tadulala and Steve Menzies.

Hull KR beat Celtic Crusaders 48-18 to leave the Super League new boys still searching for their first win in the top flight.

Clint Newton helped himself to a hat-trick as Rovers ran in nine tries at Craven Park, Michael Dobson converting six of them.

Kris Welham, Nick Fozzard, Ben Galea, Chev Walker, Liam Colbon and Michael Dobson were the other men to get on the scoresheet for Hull KR. Peter Lupton, Matty Smith and Darren Mapp bagged tries for the Crusaders.

Wakefield returned to third in the table with a 30-10 victory over Catalans Dragons.

Even controversial Australian international signing Greg Bird's early return from a court hearing in Sydney could not inspire the French side to victory.

Instead centre Sean Gleeson and stand-off Tony Martin ran in two converted tries for Wakefield in the first 15 minutes.

The Dragons fought back to 12-10 down at the interval, though, after replacement Jean- Philippe Baile and winger Dimitro Pelo crossed with Thomas Bosc adding a conversion.

But the Wildcats regained control in the second-half through Damien Blanch, Ryan Atkins and Aaron Murphy scores as they took the game away from Catalans.

Danny Orr inspired a rampant Harlequins side to victory as they routed winless Warrington Wolves 60-8 at the Stoop on Saturday.

Orr scored a try, had a hand in three others and converted all 10 Quins scores as the hosts illustrated the difficult job facing new Warrington coach Tony Smith.

Luke Dorn, Chris Melling, Luke Gale (2), David Howell, Chad Randall, Danny Ward, Karl Temata and Matthew Gafa all crossed for the Quins.

Former Great Britain winger David Hodgson scored his first hat-trick of tries for Huddersfield as the Giants edged a thriller 26-24 to bring Castleford's winning run to an end.

The Tigers were on course to make it four Super League wins in a row for the first time for seven years when they led 12-6 but the visitors demonstrated superior finishing to nudge in front by the break.

And the Giants then defended superbly despite being reduced to 12 men through the sin-binning of Leroy Cudgoe to clinch a third away win of the season.

Super League champions Leeds found their best form of the season to thrash Wigan 34-10 and open up a two-point lead with a fifth win from as many matches.

The Rhinos had failed to really impress despite winning their first four games but they were back to their clinical best against the Warriors, combining aggressive forward play with slick running and passing by their backs to delight a 17,677 crowd.

Fresh from a 44-10 rout of Bradford, Wigan were looking to make it four league wins in a row at Headingley but they were simply swept aside in a blistering opening by the champions, who raced into a 22-0 lead inside half an hour to put the result beyond doubt.

Shaun McRae was powerless to prevent Salford sliding to another dismal defeat on his return to Knowsley Road as St Helens cantered to a 38-12 victory with a seven-try blitz.

Australian McRae enjoyed a highly successful spell as Saints coach between 1996 and 1998 but he is finding life altogether tougher back in the big time with Salford.

The City Reds were 38-0 behind by the time full-back Karl Fitzpatrick and debutant Andrew Thornley crossed the line in the last 10 minutes to give their supporters reason to cheer.

The scores were deserved as McRae's men never lost heart and actually showed a marked improvement on their woeful showings in their three previous outings.
