Taffs Well remained on course for promotion to Division 3 South East, with a 26-11 win at Rhiwbina.
Tom Lowe gave the home side an early lead with a penalty goal, as Taffs Well took time to settle their nerves but a fine try by player-coach Steffan Edwards was just the tonic the side needed. Daryl Mota kicked the conversion for a 7-3 lead.
Lowe kept Rhiwbina close with his second penalty to leave his side 6-7 down at the break.
Mota , who was showing remarkable coolness for a player who had never kicked before, put over a penalty, and that was followed by a second try from Edwards, again converted by Mota, to increase the lead to 17-6.
Fullback Mike Baptiste then scored a fine solo try having run from deep in his own half. This was again converted by Moto, who had not missed a kick all afternoon.
But as Taffs Well ran from deep looking for their forth try and a bonus point, they were caught unawares and Richard Myers picked up the loose ball to score a consolation try for Rhiwbina.
Taffs Well's last two games are both against Pontyclun on Wednesday at home (kick off 7.15 ), and then on Saturday the return fixture at Pontyclun.
Nearly 40 players were involved in the first Wales Under 18 training session of the season. WRU National Performance Manager Gethin Watts is excited at the potential shown by the group and expects the Regional Under 18 Championship to hone their skills even further.
