Tony Mowbray’s side made an electric start as goals from Jack Clarke and Pierre Ekwah put them two goals ahead inside seven minutes.
Ekwah then added a third with a long-range strike on the stroke of half-time, before Bradley Dack netted a fourth shortly after the interval.
Finally, Chris Rigg put the icing on the cake with the fifth goal in stoppage-time by heading home Jewison Bennette’s cross.
