Angus began his career with YMCA at 15 in 1982 and finished at senior level in 2016 with 12,532 runs and 314 wickets. He made his Ireland debut in 1990, making 69 on debut v MCC and another 50 against Scotland that summer.

After struggling with form during the next few years, in 1996 he found his feet. He scored 99 and 94 against Wales, and the 148 against MCC. That was the first of his four centuries for Ireland (his most memorable was against a South African attack that included Allan Donald and Shaun Pollock). He was an all-rounder in the early part of his career, taking 5 for 26 on debut, but never bowled after 1995. He was appointed captain in 1998 and led his country on 40 occasions. He retired in 2000 and signed off with his fourth century.
