Having come up through the junior ranks at Llantwit Fardre, Morgan Sieniawski was drafted into the Blues Academy from where he was allocated to Cardiff RFC, and won international honours with Wales from youth to under 20 level.
Upon his release from the regional academy in 2017 Sieniawski joined up with his local club Pontypridd and proved himself to be a consistently outstanding performer, covering all positions across the back row.
His top form at Premiership level earned Sieniawski a deserved call up to the senior Wales Sevens squad in 2020, featuring in a number of World Series tournaments. Following the disbandment of the national sevens set-up, he decided to take a direct return ticket to his local club Pontypridd.
His homecoming coincided with a pressing of the restart button as a player, converting from the flanker to centre position.
Morgan Sieniawski is employed with the family motor repair company in Pontypridd.
