Inglis was the winner of the first World Masters tournament, still considered by many as the most prestigious darts competition.
In 1974, Inglis won the inaugural Phonogram World Masters, defeating Harry Heenan 3–2 in the final.
The following year he was a Unicorn World Darts Championship finalist, and was runner-up in the Indoor League – which was televised by Yorkshire TV - to Conrad Daniels.
For two successive years in the mid-1970s, he won the Man of the Match award playing for England in the Home Internationals.
On 11 November 1975, at the Broomfield Working Men's Club in Devon, England, Inglis entered the Guinness Book of Records by throwing a 19-dart 1001 game.
