The Ystrad wing was in devastating form as he plundered four of his side’s seven tries in a game that swung totally in favour of the visitors after the break. The teams changed ends with the Wanderers trailing by a mere three points at 12-9, but Ystrad scored 31 points in the second half.
As well as Williams’ four try salvo, the home side conceded tries to Ystrad skipper Alex Webber, Morrgan Burgess and Rhys Dauncey, while Rhys Truelove added four conversions. With seven games to go they are in fourth place and have third placed Bargoed and unbeaten league leaders Pontypool still to play at home.
Pontypool were forced to come from behind three times before holding onto their unbeaten record in the Admiral Championship as they head towards a possible league and cup double.
Having held off a spirited Ystrad Rhondda at Principality Stadium to pick up the WRU Champions Cup, they found themselves stretched to almost breaking point in Narberth as The Otters gave them another tough test before going down 33-28.
Scott Matthews converted a driving line-out for the opening score before Jonathan Rogers dropped a goal for the home side. Ilan Phillips bagged the first home try, which Nick Gale converted, and then Fraser Jones scored on his debut to put the home side 15-5 up midway in the first half.
Tries from Matthews and wing Matt Powell enabled Pooler to regain the lead, but a Gale penalty made it a one point game at the break. The visitors lost try scorer Powell to a yellow card and a try to Lewys Gibby which Gale improved to regain the lead at 25-19.
Back came Pooler with a penalty try before Gale kicked another penalty to put The Otters back in front in the 65th minute. Pooler finally made things safe with a Ieuan Jones try and a conversion and penalty from Jarvis to win a thriller 33-28.
Neath skipper Ryan Evans marked his 100th appearance for the Welsh All Blacks with a try in their 28-20 win at Maesteg Quins, while Bedwas head coach Steffan Sankala had to put himself on the replacements bench or the game with Trebanos.
The ‘Was had 15 players on the injury list and then lost Harry Oliver before kick-off with a suspected appendicitis. Trebanos were also low on numbers and were forced to go to passive scrums, and down to 14 men, after 24 minutes when they lost a prop.
The home side notched three tries in the first half as they raced into a 19-0 lead and Dale Rogers brought up the bonus-point with his second of the game early in the second half to make it 26-0. Trebanos, now with three youth team layers on the pitch, briefly rallied to cut the gap to 12 points with tries from Evan Davies and Evan Kneath, but James Dixon rounded things off with a fifth home try to make it 33-14 in the end.
Cardiff Met were too strong for Ystalyfera on the road as they ran out winners by 45-17, while Bargoed won 21-7 at home against Tata Steel and Beddau triumphed 39-17 at home against Cross Keys.
