Not the best of performances by a long way, as NEC Harlequins struggled to beat the part-timers from Caerphilly 31-27 despite scoring a try in the opening minute through winger Ben Gollings, who ran in behind the posts following a precision pass from Nick Duncombe. Nathan Williams easily adding the extras.
Caerphilly flank forward Gareth Jones hit back quickly for the visitors, with the first of five tries, and if they had possessed a goal kicker then the Welsh strugglers might well have won their first game of the season.
Former Oxford Blue Seb Fitzgerald squeezed over for a second try for the home side, also under the posts after 11 minutes that Williams converted for a 14-5 lead, but Caerphilly again hit back with a second score from Jones that again went unconverted.
A searing 30 yard break by Duncombe allowed Gollings to collect his double as Quins looked to re-assert themselves midway through the half, but Caerphilly refused to go away and on loan lock Nic Rouse grabbed a third try for the visitors that scrum half Allen Chiltern converted, which pegged the home side back to 21-17 at the break.
An Andrew Williams try immediately after the interval then saw Caerphilly take the lead, that they held for almost 15 minutes before Jim Evans showed that he has a phenomenal turn of speed to run in from 30 metres.
Nathan Williams added the conversion and a penalty to ease the home side more than a score ahead at 31-22, but a late score from replacement hooker Feao Vunipola, which again went unconverted, set-up a grandstand finish that almost saw Geraint Lewis grab a winning score right at the death.
Final score, 31-27.
