A storming second-half performance from the Blackwood forwards saw the Gwent side through to a comfortable victory at Glanyrafon Park and inflict a sixth defeat of the season on the struggling Drovers.
The visitors held the upper hand for much of the first half to establish a 10-point advantage on the half-hour thanks to a try by left-wing Jason Evans converted by fly-half Peter Lloyd followed by a Lloyd penalty. At that stage, Blackwood had hardly entered the Llandovery half, but with the heavier home eight gradually gaining the ascendancy, a couple of penalties from full-back Dean Brown reduced the arrears before the interval and Llandovery wilted badly in the third quarter.
Blackwood No 8 Jamie Sims put the home side in front for the first time after 50 minutes with an unstoppable burst from a tap penalty and within eight minutes his brother Wayne had followed his example. Debutant outside-half Tom Price converted the latter try and Llandovery's hopes were almost dead and buried.
It was quick thinking from Sims, picking up from the base of the scrum, who provided scrum-half Wayne Bray with try No 3 as Blackwood began to run riot and further tries followed from flanker Martyn Ackerman and hooker Rhys Williams. Llandovery were awarded a consolation penalty try by Spanish referee Mr Deluca in the final minute.
