Lunt scored a try and took home the man of the match award, while Sio was also to the fore, with a try of his own and another fine performance.
“I thought it was a bit scrappy today, probably because of the intent both teams had,” Webster told his club’s official website.
“Widnes came ready to play, they were tough and physical and they threw their bodies in. It was a bruising encounter out there.
“It wasn’t a classic with the ball because it was two desperate teams today. The pleasing thing for me was Widnes had a long time on our try-line and we were able to withhold it.
“We spoke all week about how our own tryline defence had to mean something and we stuck to that.
“Through those periods I was still confident that we could hold out – that hasn’t been the case over the last month. Hopefully that will still improve next week and as the season goes on.
“I thought it was a massive effort from Ken Sio. He dislocated his shoulder last time out and to come back and not only play, but play the way he did to bust tackles and throw his body in.
“I thought he was immense. We also had James Greenwood who hasn’t played for a month on that right edge, making over 50 tackles I think.
“Shaun Lunt was outstanding for us. I don’t think there is a game this year where he hasn’t been good. That position is so vital, when to or not to pass, left or right, scanning numbers, but he’s also a threat with the ball too and can break tackles by himself. He came up with some really big plays. We’re a better team when Shaun plays.”
