High-flying Llanelli held on for a memorable victory over spirited Pontypool, as Tom Hancock missed a drop-goal for victory.
Pooler are languishing below mid-table but managed a blistering start at Parc Y Scarlets, scoring five tries before half-time.
But after the exertions of an inspiring see-saw encounter in which eleven players touched down, fly-half Hancock pushed his last-gasp kick wide to allow Llanelli a thrilling 47-45 win.
Cross Keys brushed Bedwas aside 46-15 at Pandy Park, as Jamie Davies and Nathan Trowbridge grabbed a brace of tries apiece.
Cardiff’s disappointing form continued as Newport triumphed over the Blue and Blacks 27-21. Jamie Leadbitter scored twice for the Black and Ambers to secure victory.
