THE Merseysiders grafted their way to a well-earned bonus win with a first-half display that brought four tries.
A strong wind slightly favoured the hosts in the first period with stand-off Liam Reeve providing the ideal start with a penalty after 10 minutes.
After two away defeats on the trot, this victory by Waterloo was a real tonic.
Despite being reduced to 14 men in the second period with centre Andrew Trotter sin-binned, when the Yorkshire visitors notched a try by wing Alex Orr followed by one from flanker Jimmy Stewart, Waterloo never looked as if they would crumble after their first-half performance.
Wing James O’Brien was the opportunist.
After 15 minutes he nipped over the line for the first of his two tries with visiting full-back Tom Hodson responding with a penalty.
O’Brien was again in the frame slotting over a penalty before Carl Nolan sneaked over near the corner.
The hosts continued to show determination and a 28-3 lead at the interval provided the platform for success.
