Fresh from their stunning quarter-final upset of Cardiff University, Risca will fancy their chances of reaching the SWALEC Plate final after drawing Tredegar Ironsides in the semi-finals.
SWALEC Plate - semifinals
Ammanford v Rhydefelin
Risca v Tredegar Ironsides
SWALEC Bowl - Semifinals
Lampeter v Glyncorrwg
Morriston v Pontyclun Ties to be played weekend of 18/19th April.
In the other semi-final, Ammanford, who brushed aside Newcastle Emlyn 28-15, will take on Rhydefelin who battled to a 21-15 victory over Mountain Ash.
Chris Fowler, secretary of Rhydefelin, said, "Ammanford are like ourselves in the league where we are both struggling in our divisions at the moment. We just hope the Plate win over Mountain Ash will kick start our season. To get to the final and play at the Millennium Stadium would be very special for the club."
Division Three West outfit Lampter will be hoping to reproduce their stirring SWALEC Bowl display from their quarter-final when they take on Glyncorrwg in the semi-finals.
Lampeter had to come from behind against Usk before prevailing 28-24 while the other semi final sees Morriston take on 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.
