The ever improving Catalans Dragons took advantage of a Hull KR side with perhaps one eye on Monday's big derby at Hull to record a 34-20 victory at Craven Park.
But Stanley Gene and Byron Ford tries, both goaled by Gareth Morton, put the home side in front at the break.
But 24 unanswered points in the first 25 minutes of the second half saw the Dragons open a gap that proved too difficult to claw back.
First, Vincent Duport crashed over on 47, closely followed by Clint Greenshields (53), Kane Bentley (56) and Stacey Jones, who wrapped up the Dragon' scoring on 64 minutes. All four tries were converted by Thomas Bosc, and the Dragons had a 22 point lead.
Scott Murrell and Luke Dyer grabbed late consolations for Hull KR, who will have hoped to have saved enough energy to put on a fight in what promises to be a mammoth encounter in Super League's first ever Hull derby on Monday.
As for Catalans, their march up the table continues with another impressive away showing, following up their excellent win away at Bradford two rounds ago.
