Revitalised Swansea hit back in style to show that their faltering quest for Celtic League title and retention of their Welsh-Scottish prize might not be the lost cause recent results suggested.

Fly-half Stephen Jones was Llanelli's saviour with last-gasp winners to sink first Ulster and then Pontypridd.

But not even a clean sheet of seven penalty goals in as many attempts could rescue his side a third time as they tossed away chances galore.

But Swansea were worthy of their spirited success in a typical blood and thunder derby between Wales's oldest rivals.

And they did it without the services at times of locks James Griffiths and Tyrone Maullin, who were sin-binned within a minute of each other in the first half.

Even with 13 men their resistance never cracked and Llanelli's only reward came through Jones' boot.
