A local Ponty boy, Morgan Sieniawski was drafted into the Blues age grade system and then allocated a place in the regional academy, in the meantime gaining international honours with Wales from youth to under 20 level.
Given a placement with Cardiff RFC, Sieniawski was a stand-out performer at openside flanker during the 2016-17 Premiership campaign.
Released by the Blues in the summer of 2017 Sieniawski signed up for his hometown club Pontypridd, following in the footsteps of his elder brother Jordan. His immense contribution during his first season with the club was reflected in a nomination as both Forward of the Year and Players’ Player of the Year.
Morgan works with the family auto-repair firm.
