Catalans Dragons climbed to second in Super League with a 40-0 win over Hull KR at the KC Lightstream Stadium.
It was their fifth successive win and their third on the road.
This was a Rovers' first game back on home soil since conceding four tries in the final quarter of their Good Friday Derby against Hull FC.
And they started this game in the same manner they ended that game by conceding tries.
Catalans got on the front foot right from the opening kick-off with Willie Mason taking the first hit-up in his return to Rovers where he spent a brief spell before an acrimonious departure in 2010.
At the end of the first set Jodie Broughton touched down in the right hand corner. Pat Richards missed the conversion, but the visitors led 4-0.
From the restart, Richards won a penalty by defusing the kick with his foot on the touchline.
From the resulting penalty, Vincent Duport scored his side's second try of the night at the opposite end of the side of the pitch. The angle suited Richards who converted for a 10-0 lead.
The Dragons dominated the first 10 minutes and 18 seconds in which they scored twice, forced a goal line drop out and an error to starve Rovers of and possession.
When they did get their hands on the balls, Rovers could not get over the line. After weathering the KR storm, the Dragons got back to scoring tries.
Broughton strolled through for his second of the night in the 22nd minute before Christian Inu jumped higher than Kieran Dixon to score the French side's fourth try. Richards converted both to push the visitors 22-0 in front.
Things got worse for Rovers just before half-time when Gregory Mounis picked up a pass from Olivier Elima to score from close range. Richards' conversion made it 28-0, a lead they kept going in to the half-time interval.
Rovers were caught napping nine minutes into the second half when Richie Myler, who was in great form throughout, nipped through from two metres out. Richards added the extras for a 34-0 lead.
Ben Cockayne's sin binning summed up Rovers night in the 54th minute.
The only thing missing from the Dragons game was a try from Mason. It duly came in the 55th minute when he used his gangly frame to ground the ball whilst being tackled by three Rovers defenders. Thomas Bosc this time added the conversion to make it 40-0.
With the points secured for the French side, the game petered out into a game with little excitement.
