Pontypool's wonder start to the season continued as they fought to the end to beat Bridgend Athletic 31-24 having trailed 21-10 at the break. First half tries from Dan Howells, Ross Parsons and Dan Belu, all converted by Steve Lewis, had given the visitors a handy lead at the break.
But Pontypool turned on the style in the second half and Jordan Williams crossed for the fourth try to ensure a second successive bonus point. Niall Martin converted all four tries and ended with 11 points from the boot.
Beddau picked up a win on the road at newly promoted Tondu, skipper Glen Slater's try helping to secure a 17-13 victory, while Llanharan had outside half Codey Rees to thank for their 33-16 win at Blackwood.

Bev Howells kept his nerve to kick the winning goal with the last kick of the match to steer Newbridge to their first win of their 125th anniversary season, a 23-20 home triumph over Tata Steel. The centre had earlier crossed for one of his side's three tries.
The home side were 20-10 ahead at the break, but the visitors hit back to level the scores at 20-20. Then Howells stepped up to steal the glory.
