RAWMARSH put the disappointment of their losing return to action behind them with a comfortable 41-0 win over depleted Wibsey at Barbers Avenue.
The Warriors suffered after their 10 week layoff but were back in the swing of things last weekend.
Wrong decisions in the centre meant good early attacking play for Rawmarsh was wasted with the visitors happy to get bogged down in a forwards battle.
The deadlock was eventually broken when Number 8 Harper crashed through a sea of bodies to score under the posts.
Rusty Kirkland picked up a try after some decent movement saw the ball moved quickly out wide.
Further tries came from captain Matt Allott and two for John Howett, with Cooper getting in late on for a season opener.
On Saturday the Warriors visit Adwick le Street in a 2.15pm kick off.
