Giants statement, Rhinos win
Huddersfield took a giant leap towards the League Leaders' Shield with a win at Wigan, while Leeds and St Helens also claimed victories.
Huddersfield claimed a three-point lead at the top of Super League with an impressive and psychologically important defeat of title rivals Wigan.
Tries in the second half from Brett Ferres, Scott Grix and Aaron Murphy saw the Giants pull away to land a potentially crucial blow in the race for the League Leaders' Shield.
The sides had matched each other in the first period with a Wigan side lacking Sam Tomkins scoring through Sam Powell and Josh Charnley - his 39th try of the season - and Huddersfield responding through Murphy and Jason Chan.
It was Huddersfield's fifth win in six visits to Wigan and answered questions over their big game temperament, although the Warriors - Challenge Cup finalists this month - live to fight another day.
Leeds consolidated fourth spot in the Super League table with a seven-try 42-16 victory at second-from-bottom Salford.
Kallum Watkins scored two touchdowns and skipper Kevin Sinfield kicked seven goals from seven attempts for the Rhinos who have now won the last 10 clashes against Salford since their shock Headingley defeat in 2009.
Zak Hardaker, Rob Burrow, Carl Ablett, Ben Jones-Bishop and 17-year-old debutant Elliot Minchella were also on the scoresheet for the defending champions, who led 24-6 at the break.
Ashley Gibson, Lee Gaskell and Theo Fages dotted down for the hosts.
Francis Meli scored twice as St Helens ran in seven tries in a 38-10 victory over Super League's bottom club London Broncos at Langtree Park.
Adam Smith, Louis McCarthy-Scarsbrook, Tom Makinson, Anthony Walker and Jonny Lomax ran in the other scores, with the latter adding five goals. Daniel Sarginson and Iliess Macani got over for London.
