The Scarlets under 16s will be hoping to make it three successive victories against the Ospreys this season when the sides meet in tomorrow night's WRU Age Grade Championship final at St Helens.
Beaten only once in qualifying, the Scarlets edged out their neighbours 17-12 at Parc y Scarlets back in October before edging them out, once again, 20-12 at Llandarcy last month.
Now, the teams will go head to head in what promises to be another outstanding Age Grade spectacle.
For the Scarlets, it's also an opportunity to make up for the disappointment of their under 18s who were narrowly beaten by the Blues in last month's final at the Brewery Field.
However, the Ospreys are past masters at winning the vital Age Grade finals and they will hope to redress the balance this season by putting one over on their closest rivals.
Scarlets team manager Wyn Thomas said; "They boys have done particularly well this season and have developed well, boith individually and as a squad.
"We are delighted to be in the final and would love to finish the campaign with one more victory."
Ospreys team manager Graham Court said; "I suppose we are hoping that it's third time lucky having gone down narrowly to them twice this season.
"The competition has been a really good advert for the Age Grade system and fingers crossed, it will finish on a high for us."
Evan Yardley will lead the young Ospreys from hooker, whilst for the Scarlets, flanker Sion Bennett is named as skipper.
