THE Royal Grammar School's under-18 rugby team took just eight minutes to bulldoze their way into the last 16 of the Daily Mail Schools Cup with a demolition job on St Brendans.

Colin Tattersall's side stunned their Bristol-based opponents with a ferocious opening salvo during which they stacked up 15 points on their way to a 23-7 victory.

The RGS will now entertain St Peters of Gloucester with a place in the quarter-finals of the competition, which ends at Twickenham, at stake.

Quick-fire tries from John Hammond and John Ray rocked the Bristol team back on their heels and a conversion and a penalty from Ed Garrow ensured the RGS had built up a 15-0 cushion inside the first ten minutes.

St Brendans refused to lie down though and they reduced the arrears just before half time with a converted try.

But just as they looked as though they might be capable of staging a dramatic comeback, the RGS snuffed that out with another Garrow penalty.

His score was the straw which broke the camel's back and St Brendan's lost their resolve and discipline.

They had two players sin-binned at different times and the RGS took full advantage of their chaos when Adam Slocombe finished them off with a try.
