Steve Price got his first win as Warrington coach as two Ryan Atkins tries saw off local rivals Widnes 18-10.
After defeats to Leeds and Huddersfield, Price needed a win and he got it, though the game may well be remembered for the thunderous accidental collision between referee Phil Bentham and Widnes captain Chris Houston.
Bentham had to leave the field after Houston – chasing a kick – inadvertently clattered him from behind – with the ‘ref cam’ showing the full effect of Bentham’s tumble.
Away from that, Atkins was in sparkling form. His two tries, one either side of half-time, were crucial as the Cheshire derby went the way of the Wolves.
Warrington had won their last nine meetings with Widnes, and after building up an 18-4 lead midway through the second period, they had just enough to secure the win, digging deep to hold off a Vikings fightback.
Warrington edged their noses in front at the break with a six-point advantage after early tries from Atkins and the outstanding Stefan Ratchford.
The Wolves’ first came after they had absorbed some significant Vikings pressure and when they finally got themselves into some attacking positions, Dec Patton hit the button with precision kick which was caught by Atkins for a well-worked try.
The next came courtesy of a solo effort from Ratchford who danced his way over from close range after the Vikings were caught short on the right edge.
Bryson Goodwin knocked over the conversion to push Warrington to a 10-0 lead that had come from nowhere.
The Vikings were never out of it and they had some promising spells with the ball but on too many occasions they could not find the killer pass.
Greg Burke came closest for the Black and Whites with an attempted barge over but Warrington’s goal-line defence was up to the task.
The conversion was missed by Tom Gilmore but Widnes were within touching distance again.
After Atkins had collected his second, thanks to an excellent cross-field kick from Ratchford, the game was halted after Houston collided with referee Bentham.
Bentham was knocked to the ground heavily and had to leave the field of play, with reserve referee Scott Mikalauskas taking over the whistle duties.
The break seemed to unhinge the Vikings and they temporarily lost some composure that resulted in Goodwin landing a further two points with a penalty to inch Warrington closer to the finishing line.
Tempers began to fray and when Inu clashed with Ben Currie but when Widnes found their feet again Gilmore laid on another kick-try for Inu to give Betts’ side a flicker of hope.
Ted Chapelhow thought he had got another Vikings score as he broke through Warrington’s tired defence but he fumbled the ball over the line that extinguished Widnes’ hopes.
The Wolves made things harder for themselves in the closing stages as Mike Cooper completed a professional foul on Danny Craven which saw him sin binned, but they managed to hold on.
