Tom Clarke scored his first goal for Huddersfield as they secured a first win in nine league games.
The 18-year-old curled in a terrific shot with the outside of his right boot early on to put Huddersfield on course.
Clarke, a makeshift midfielder, was outstanding throughout and created chances for Pawel Abbott, Andy Booth and Danny Schofield.
Huddersfield finally wrapped up the win when Schofield tapped in after seeing his penalty saved by Lee Jones.
