Penybont secured 5th place after they beat Haverfordwest 2-0 as phase one of the Cymru Premier comes to an end.
Goals from Sam Snaith and Mael Davies saw the home side come out on top.
Haverfordwest required a victory in the last game of phase one to have any hopes of finishing in the top six.
Penybont were worthy winners with Haverfordwest not creating many clear-cut chances in the game.
The first chance of the game fell to Kostya Georgievskey, as a long-range pass from Kane Owen landed at the feet of the winger, who tried to cut in and shoot but the effort was blocked by the away side.
In the 25th minute, Georgievsky had a half-chance to score after a headed ball from Sam Snaith went towards Georgievsky but he failed to connect with the ball.
Haverfordwest had to deal with a big blow in the first half as goalkeeper Matthew Turner, on loan from Leeds United, was forced off after a collision with Bont full back Owen.
Penybont opened the scoring as striker, Sam Snaith, met a wonderful corner from Owen with his head to put the ball in the back of the net to put the home side one up.
The best chance of the game for Haverfordwest came from a one on one chance for Ben Fawcett, but he wasn’t able to get a shot off after Mael Davies swept across and made a huge tackle to deny the goal-scoring opportunity.
Penybont had a great chance to double their lead after Snaith attempted an overhead kick, which was tipped onto the crossbar by the replacement Haverfordwest keeper, Wojciech Gajda.
Soon after this, Mael Davies scored the second for Bont with a 25-yard strike which found the bottom corner.
Haverfordwest had a opportunity to score with Marcus Griffiths, who took it around a defender but managed to get a shot off, but it was an easy save for Bont keeper Ashley Morris.
Davies, who was fantastic all game, had another long-range shot in a similar position to his goal but this time he failed to find the back of the net.
The result sees Penybont confirm their spot in the Championship Conference for phase two as well as a European play off.
