Castleford have thrashed Wakefield while Hull KR have been thumped by Warrington.
Castleford Tigers 40 Wakefield Wildcats 6
Castleford produced a dominant seven-try performance to hammer neighbours Wakefield 40-6.
The Tigers were forced to settle for a draw in round one after Josh Mantellato’s last-minute heroics for Hull KR but there was no such drama in front of a crowd of 9,761 at the Mend-A-Hose Jungle on Sunday afternoon.
Stuart Howarth opened the scoring for Wakefield but the Tigers went into the break with a commanding lead after converted tries from Denny Solomona, Ben Roberts and Luke Dorn.
The next score was crucial and there was no way back for the Wildcats after Oliver Holmes crossed, with the back-rower adding a second following a try from Adam Milner and another for Solomona.
Wakefield managed to keep the Tigers scoreless in the final 15 minutes but they were left to reflect on back-to-back defeats.
Warrington 38 Hull KR 8
Tom Lineham bagged a hat-trick as Warrington followed up their opening-day win at Leeds with a six-try 38-8 success over Hull KR.
Lineham, a close-season wing capture from Hull, went over three times in the second half after his side led 12-0 at half-time.
Kurt Gidley, man of the match at Headingley was again in outstanding form on his first home appearance.
He created the opening tries for Ben Currie and Joe Westerman before being sin binned just before the break.
The Aussie stand-off also slotted over seven goals from seven attempts with the Wolves other try a solo special from Daryl Clark.
Depleted Rovers kept plugging away and deserved their tries through Ian Thornley and Kieran Dixon but never looked like winning.
