Billy Pasco progressed through grassroots rugby with Woodbridge RFC and he attended Oundle School, where he developed into a powerful ball‑carrier and reliable defender.
His leadership qualities shone through when he captained Saints’ Under‑18s during the 2023/24 season, and in the summer of 2024, Pasco was rewarded with a senior academy contract.
He made his first-team debut as a replacement in the Premiership Rugby Cup in a victory over Nottingham in November 2024. He then earned his first start a few months later in the same competition against Leicester Tigers, and scored his maiden senior try in a home win over Coventry, underlining his quick adaptation to senior rugby and marking him as one of the Club’s bright young talents.
Internationally, Pasco has been recognised at Under-18s level for England, and received a call-up to train with the England A squad in February 2025 ahead of their fixture against Ireland A.
