In September 2022, Rooney progressed to Castleford's academy squad.[5] During the 2023 academy season, he made 11 appearances and scored 10 tries and 1 goal, as well as a further 5 appearances and 1 try at Reserves level, and was named Academy Player of the Year.[6]
In September 2023, Rooney was introduced into first-team training with the Castleford senior squad, and was assigned squad number 47.[10] On 22 September, aged 17, he made his Super League debut for the Castleford Tigers against the Leeds Rhinos in the final round of the season.[11][12] His performance in defeat earned praise from head coaches Danny Ward and Rohan Smith[13] as well as the travelling fans.[14] Rooney said of his debut, "All my life I've been working towards that moment, it was a big thing for me and my family."[15] He became the first 2006-born player to feature in the Super League.[16]
In October 2023, Rooney was included in Castleford's listed first-team squad ahead of the 2024 season,[17][18] one of only two fullbacks alongside Luke Hooley.[19][20] He would be following a hybrid programme between the academy and first-team environments to support his development.[21] In December 2023, it was announced that Rooney had signed his first professional contract with Castleford, agreeing a three-year deal.[22][23] He required surgery for an ankle injury suffered in January,[24] which prevented him filling in for the injured Hooley before the signing of Tex Hoy.[3] On 1 August, playing as a winger, Rooney made his second senior appearance and scored his first Super League try in Castleford's home loss against Leigh.[25][26]
