LONDON - Australian Dan Sarginson helped Wigan Warriors end St Helens' 100 per cent start to Super League as he notched one of their five tries in a 33-14 win at Langtree Park.
The Warriors went ahead through captain Sean O'Loughlin but the Saints were level when Tommy Makinson crossed to become the first player to score ten league tries this season.
Excellent running from Blake Green then set up Sarginson in the corner, before Liam Farrell grabbed the first of his two tries for the Warriors.
Makinson and centre Jordan Turner reduced the gap for the hosts, but Wigan's Farrell and Joe Burgess ensured there would be no comeback from the league leaders.
Leeds are now just a point behind the Saints after a Rob Burrow-inspired 46-6 victory over Bradford on Thursday.
Burrow, scored a try late on to seal Leeds' biggest winning margin ever at Odsal.
Francis Meli scored a hat-trick for Salford but the former Auckland Warrior couldn't prevent the Red Devils falling to a 42-22 home defeat to Huddersfield Giants yesterday.
Aaron Murphy also notched up a hat-trick for the Giants, while Shaun Lunt, Danny Brough, Jermaine McGillvary and Chris Bailey also helped themselves to tries for Huddersfield in a comprehensive performance.
Two tries apiece from Richard Owen, Daryl Clark and Scott Wheeldon kept Castleford in third place with a 43-20 win away at Wakefield.
Owen scored two of Castleford's five first-half tries as the Tigers raced into a 26-12 lead at the break.
The Wildcats fought back to within six points but Clark and Wheeldon completed their doubles to seal victory for the visitors — who also had former Sydney and Canberra wing Justin Carney among the scorers.
Elsewhere on Friday, the Monaghan brothers grabbed a try each for Warrington Wolves in their 44-6 rout of sorry Widnes — Joel and Michael both going over in the first half at the Halliwell Jones Stadium.
