Joel Moon continued his fine recent run with a try as Leeds Rhinos powered past Hull KR 44-10 to stay in the top four of the Super League.
The Rhinos took control in the opening 40 minutes, running in four tries through Ryan Hall, Brett Delaney, Zak Hardaker and Mitch Achurch to lead 20-6.
Cory Paterson had responded for Hull KR after Hall's early score, but that was as good as it got for the ex-Newcastle Knight and his teammates.
Moon, who spent two seasons in the NRL with the Brisbane Broncos, went over two minutes into the second half to stretch the visitors' lead and they cut loose through Kallum Watkins' double and a final try from Ian Kirke.
Warrington Wolves kept themselves just above the Rhinos as they comfortably saw off Bradford Bulls 32-4.
Warrington had the better of the first half thanks to tries from Simon Grix, Ben Currie and Chris Riley but Brett Hodgson was unusually wasteful, adding just one goal.
Adrian Purtell scored Bradford's only try of the half as they trailed 14-4 at the break.
In the second half the Wolves were rampant though, running in four tries, including one for former Kangaroo Joel Monaghan, with Hodgson adding another two points to seal the win.
On Saturday, Huddersfield Giants stayed in second after a 28-20 win over Catalan Dragons, despite the best efforts of Zeb Taia.
The 28-year-old scored the Dragons' third try as they battled to a 16-8 lead just after half-time.
But the Giants, led by the impressive Danny Brough, fought back despite the loss of scrum-half Luke Robinson who was sent off for a late high tackle on Morgan Escare.
Elsewhere, Michael Witt kicked the London Broncos to a 21-14 win over St Helens, notching four goals, as well as a drop goal.
Michael Robertson and Chris Bailey were among the try-scorers for the Broncos, while Anthony Laffranchi, the forward with five Kangaroo caps to his name, went over in vain for Saints.
In the other game on Saturday, Salford City Reds got the better of Castleford Tigers 34-30 in a 12-try thriller.
Vic Mauro and Ryan McGoldrick both crossed for the Reds but the Tigers kept in touch with six tries of their own, including one for Justin Carney.
On Friday, league leaders Wigan were grateful to Pat Richards, who this week announced he would be returning to the NRL with Wests Tigers, as he kicked 12 points in a 28-20 win at Hull FC.
Sam Tomkins scored two tries, with Josh Charnley and Iain Thornley getting the others and Tom Lineham's hat-trick in vain.
Paul Aiton scored one of five tries as Wakefield Wildcats edged out Widnes Vikings 28-26.
