Players and spectators enjoyed the sunshine at Llangennech with the conditions ideal for the open running rugby produced by both teams.
While the spectators basked in the almost summer like conditions, the players had to put such pleasures on hold as each team sought the advantage.
The visitors produced some stunning rugby from the start and were awarded a penalty after three minutes near the touchline on the 22.
Fullback Gareth James had a great effort but his kick hit the bar.
Llangennech outside-half Mark Jones converted a short-range penalty after eight minutes to give his team the lead.
The Llangennech defence had held firm to soak up the early pressure and the Llangennech players soon revealed their propensity to counter-attack at every possible opportunity.
Gareth James had another chance to put the Otters on the scoreboard, but a long range kick from the 10-metre line sailed just wide of the posts.
Good work by the Narberth pack produced an abundant supply of possession to the three-quarters, but the danger of constant attack is that sometimes you can be vulnerable and concede a breakaway try.
This happened after 13 minutes with the Otters in a commanding position near the Llangennech line. Llan fullback Wayne Lewis intercepted an attempted pass and with his speed off the mark and stamina for the long run he just got to the line in time to cross for an unconverted try in the right corner.
Popular prop Fifipuku Faletau reduced the deficit with a try after 18 minutes in what some old stagers described as the first 'walking try' that the Otters had scored since their playing days!
Emori Katalau had won the ball in the lineout following the award of the penalty. Simon Daniel's deft kick gave the pack an ideal position to attack the left corner.
In recent weeks the forwards have been practicing the rolling maul in training. This was a case of practice made perfect as with the help of his seven colleagues in the pack 'Puku' came up from underneath the pack beaming after touching down for the catch and drive try.
It was a pressure kick for Gareth James, but he converted coolly.
The Otters continued to attack and the boldness paid off. From a three-quarter movement inside the Narberth half, Simon Daniel threw out a long flat pass to centre Deiniol Evans missing out Elgan Vittle.
Evans weighed up the situation quickly and darted through the half gap despite having a winger Andrew Jones outside.
It was a superb break and run by Evans and he finished in style in the left corner.
Once again Gareth James added the conversion points.
Fortunately for the visitors Mark Jones was off target with a penalty attempt just before the interval.
The lead changed hands at the start of the second half. Scrum-half Rhydian McGuire showed a quick pair of heels when he made a blindside break from a scrum to cross for an unconverted try in the right corner.
Within minutes, Llangennech were awarded a penalty and Mark Jones put his team in front from 30 yards.
The game was back in the melting pot despite the visitors having had the better of the first half.
Nevertheless, team spirit and commitment kept the Otters in with a shout, and midway through the second half the visitors regained the lead.
The visitors had been playing 15-man rugby throughout the game and the try justified this exciting brand of rugby.
Jason Jennings did well to win a lineout on the left touchline and the ball came across to the right until the move broke down when winger Nick Jones found his path to the line blocked.
The ball was recycled quickly and moved back out along the left and scrum-half Adrian Killa made a defence splitting diagonal break to set up a try for Andrew Jones.
The left wing seized the opportunity but was made to work for the try by the Llangennech defence, before he eventually touched down in the left corner.
Unfortunately Gareth James was unable to convert.
The rest of the game was played out in mounting excitement but the Otters held on until injury time.
The result was in the balance when Llangennech were awarded a penalty in injury time just inside the Narberth half.
There was no time for Llangennech to attempt to run the ball, so Mark Jones opted for the posts. It was a brave effort, but the kick went wide much to the relief of the large contingent of supporters who had made the journey east from Narberth.
Head coach, Rob Phillips, said: "This was an excellent performance by the boys and a number of players have commented that it was a real team effort. We exhibited a degree of control in the first half, which we have not always displayed in other games and in many ways we were unfortunate not to be further ahead at half-time.
"We must pay compliment to Llangennech for the way they came out and fired into us in the second half.
"We were making yards and penetrating their defence, but turnovers out wide cost us dear on occasions. We had a couple of set-backs when Llangennech came into our half a couple of times and picked up points. However, it was a testament to the effort that the boys showed and to their commitment that we were able to weather the storm.
"The set piece work went well, Emori Katalau had a very fine game and the back row worked well together.
"Deiniol Evans has struck a rich vein of form. With Andrew Bowen back in contention having recovered from injury, it gives us the right type of worries in selection.
"We look forward now to meeting the top sides and hopefully to give them a good game.
"Llanharan and Maesteg have built up on the success that they had at the beginning of the season. It will be a real challenge for us but hopefully we can do something against these top sides.
"It was good to see outside-half Simon Daniel back to fitness and he gave us an edge in pressure situations with his line kicking."
Skipper, Simon Daniel, commented: "It was probably our best performance of the season. We are getting better each week and continued were we left off against Glamorgan Wanderers the week before.
"This game was the best of the season without a doubt and we want Maesteg next week now more than anything.
"The way in which we played in the first half was better than anything we have shown this season but we must keep it going for 80 minutes. It was a pleasure for us to play behind the pack today, as they were simply awesome. We want Maesteg!"
Team manager, Robert Lewis, added: "We played very well in probably our best performance of the season. The pack went very well as a unit and it is difficult to remember the last time that we scored from a catch and drive in the lineout. The rolling maul worked well and the hard working training is beginning to pay off.
"Our lineout experts won our own ball in the lineout and caused Llangennech problems and the pack also scrummaged effectively, both half-backs played well and controlled the game particularly in the closing stages when it was very tight.
"Both centres played well and it was a cracking try by Deiniol Evans.
"The back three also worked well as a unit and fullback Gareth James often came in to create the extra man.
"The other pleasing aspect about the performance was the team spirit shown by the players."
