Penygraig had won both league meetings between the rival clubs in Division 3 East Central this season, but this time it was the mighty Ducks who came out on top.
Hooker Corey Jones, number eight Mackenzie Williams, inside centre Danny Connolly and skipper Matthew Lewis scored the tries. Lewis added three conversions and five penalties for a 26-point personal haul.
However, the final scoreline might have been closer had it not been for a red card shown to Penygraig prop Llew Coleman just two minutes into the final.
The win for Wattstown was the perfect send off for coach Ian Swannack, with this set to be his final season as he steps down to spend more time with the family.
Swannack led the Ducks to promotion from Division Four East Central last season and has overseen a sixth-place finish in the division above this term. Opponents Penygraig finished in fourth spot.
“Before the game, I told the boys I genuinely believed we were capable of winning,” said Swannack talking about his side’s margin of victory in the final.
“We’re a much better side than we’ve shown at this season, we’ve been really unlucky with injuries, but every team can say that. I was a little bit disappointed with the two results in the league games.
“The last game at home was literally the last play of the game, so I think we definitely owed them. I believed in the boys, and they proved me right.
“It’s our first season in Division 3 and we were comfortable, so we’ve got to be happy. We had some really big results this season and we’ve topped it off with a final win and a cup.”
Swannack though did concede that the early sending off for their opponents changed the game. In what was a full bloodied start from both sides, they came to blows after a coming together with the game less than three minutes old and Wattstown on the attack.
After the resulting melee, tight head prop Coleman was sent off, while Wattstown lock David Smith received a yellow card. A flurry of further yellow cards followed in what was a breathless first half.
Three successful penalty goal attempts from Lewis against one from opposite number Owain Davies put Wattstown 9-3 in front. After that they took full control.
Jones, Mackenzie Williams and Connolly all crossed in the first half for Wattstown, who led 31-6 at the break with Lewis adding two conversions and another penalty. Davies kicked a second penalty for Graig.
Penygraig pulled a score back through blindside flanker Alex Williams in the second half, converted by Davies, but it was ultimately scant consolation. Lewis put the crowning glory on the win for Wattstown when he ran through for their fourth try, added the extras and also sent over his fifth penalty.
“The boys have worked so hard the last few weeks, and this win is massive,” added Wattstown team manager Jamie Langmead.
“It was our day, and you can see from the crowd just how good the support is that we’ve got. Hopefully this will kick us on now into next season.”
