He went on to win 72 caps for Wales and scored 33 tries – at that time a record for Wales – and was dubbed "Merlin" by TV commentator Bill McLaren. Amongst his most memorable moments were scoring the decisive try in the 3rd Lions Test against Australia in 1989, being captain of the Wales team when they won the Five Nations Championship in 1994 and scoring a memorable try against England in Cardiff in 1993 to secure Wales their only win of that campaign 10-9. He made his final appearance against Italy in 1998.
