LAPSES in concentration cost Nestlé Rowntree RUFC as they lost 21-0 at Thirsk.

Trees looked the better side for the first quarter and almost took the lead when a John Atkin penalty shaved the wrong side of a post but poor marking at the resultant 22-metre restart saw Thirsk centre Nick Wilson race away for a converted try.

The same player then doubled Thirsk's lead with an interception try.

In a scrappy second period, a missed tackle by Nestlé's normally solid central defence saw Thirsk centre Ian Matter cross, Pete McAlmont landing his third conversion.
