The Scarlets withstood a late Cardiff fightback to claim their first United Rugby Championship win of the season 31-25 in a full-blooded Welsh derby in Llanelli.Dwayne Peel's side came into this game under intense pressure after suffering two hidings in South Africa, but after a shaky first half showed tremendous character to claim a bonus-point win over their Welsh rivals. This derby had been undermined by Wales' exhibition match against the Barbarians on the same day, meaning both sides were without a number of first-choice players, but even so it was a hotly-contested affair.Cardiff drew first blood with a lovely break from Cameron Winnett who offloaded to Harri Millard.
