Warrington Wolves had a few nervous moments before securing their place in the fifth round draw of the Carnegie Challenge Cup with a win at Leigh.
The Super League side were16-0 ahead at half-time with John Clarke, Chris Riley and Chris Hicks touching down to make sure they were not the victims of a Cup upset.
Leigh made a determined start to the second half with Ian Watson scoring a try and converting himself to cut the deficit to just 10.
But they failed to capitalise on some good chances and Warrington sealed their win with a further two tries from Kevin Penny and Paul Rauhihi, while Hicks kicked four goals from five attempts. Mike Morrison scored Leigh's second try in the dying minutes, Watson again converting.
