The village of Bedlinog will still be celebrating this morning after they secured promotion to Division One East against Brynmawr at the Recreation Ground.
The narrow 13-7 home victory may have been routine but it was a historic day for the Merthyr valley side and their 200 army of supporters who witnessed the third successive promotion to finish as Division Two runners-up behind champions Tredegar.
Bedlinog treasurer Lyn Jones said: "It's a tremendous achievement for the squad of players we've got.
"We've all been together for six years now and it's a special time for the whole village.
"It was a big step up this year and to finish as runners-up is a huge achievement. But we believe we can do ourselves proud in Division One next year."
Ian Grzalac and Ryan Jayne were the heroes in either half as Bedlinog overcame a sloppy start to achieve their dream.
Grzalac won a line-out and was pushed over the try-line by his fellow forwards before Jayne's strike on 65 minutes sparked wild celebrations to make it a Bank Holiday to remember.
