The event, in which Trigg beat his opponent Peter Kerwin in the second round, featured several big Welsh fighters, including Joe Erskine and Eddie Thomas.

After a string of wins he was invited to fight at White City Stadium in London against local boxer Tony Dove.

On 23 April 1958, Trigg lost his Welsh area title to Redvers Sangoe at Sophia Gardens Pavilion in Cardiff.

It was the start of a bad run of form which ended in Trigg's retirement from fighting after a loss to Gordon Corbett in August 1959.

After completing his National Service he married Valerie and the two took on a public house, the Coach and Horses in Caerwent near Chepstow, to which Trigg also added a gym where he trained other boxers.
