A fifth win has kept unbeaten Cranleigh among the front runners in the SOCS Daily Mail Schools Trophy.
A 25-10 win over Denstone left Andy Houston, Cranleigh's director of rugby, claiming it was the 'highest standard of rugby I've coached at school boy level.'
Second-half tries from Hayden Hyde and Hugh Tizard stretched Cranleigh's lead though Houston said the contest could have gone either way.
'They (Denstone) were the best team we've played,' Houston said about a season which has also brought wins over Brighton College, St John's Leatherhead, Epsom College and Hurstpierpoint.
