Stefan Marsh scored two tries as Widnes Vikings secured a 28-14 victory over the London Broncos.
Marsh impressed throughout as Widnes ran in five tries to get their Super League campaign off to a perfect start.
The visitors finished with the wooden spoon last season but they set about putting that right straight from the off, grabbing an early lead when Marsh took Jon Clarke's pass, cut inside and muscled over from close range.
It was Widnes who were to move further clear on the half-hour, Clarke engineering space and romping over after neat hands from the Vikings backs.
And the away side moved into a commanding position before the break, Dave Allen cashing in with a third try after the Broncos spilled an aimless kick on the last tackle.
Tony Rea's men finally got on the board on 64 minutes, profiting from a loose pass that went to ground with Kieran Dixon scooping up and skidding home.
Further late scores saw Frank Winterstein rumble home for the visitors and Chris Melling and Dixon burst over late on for the Broncos, Marsh rounding off the scoring.
