Ash joined Rovers in 2017 having initially started out with local club Curzon Ashton.

Highly-rated and eligible to represent Wales and England, it was with England where Phillips earned his first international cap when he played for the Under-17s in the win over Portugal in the semi-finals of the Syrenka Cup.

Progressing to be a part of Jon Dahl Tomasson's plans in pre-season in 2022, Ash made his first-team debut in the 4-0 Carabao Cup win over Hartlepool United at Ewood Park in August 2022.
