Fylde took the lead on the half hour.
Full-back Danny Carleton worked the opening with a mazy dash down the right-wing that troubled the Rosslyn Park defence no end - Fylde then deftly switched the point of attack across the field with some slick handling and it ended in style with Ben Gregory finding try-scorer Briers, who dashed in at the corner. Smith was wayward with his conversion (13-10).
On 38 minutes Fylde nudged further ahead thanks to a Smith penalty (16-10).
