Striker Ben Armour signed with the development squad in September 2016 and made his first-team bow as a substitute away at Dunfermline Athletic on Saturday 29 April, replacing Lawrence Shankland in the 85th minute.
Duffy challenged the teen to continue his progression and push for more top-team participation next term, and he responded by netting his first senior goal in a pre-season friendly against Stenhousemuir in July.
After four competitive substitute appearances for the senior side, Ben signed a contract extension in November 2017 that will keep him with the club until 10 June 2018.
