Steve Mounie's scored a first-half double as Huddersfield ended a run of four consecutive defeats with victory over Brighton at John Smith's Stadium.
The striker, recalled to the starting line-up by head coach David Wagner, put the hosts in front in the 12th minute when he bundled home Chris Lowe's corner from close range after a flick-on at the near post.
The 23-year-old added his second two minutes before half-time when Brighton goalkeeper Mathew Ryan failed to stop his tame low header following another corner.
Brighton struggled to create any meaningful chances and did not have a shot on target until a weak effort from distance by Jose Izquierdo in the 79th minute.
The victory for Huddersfield, their fifth of the season and first since 4 November, takes them above Brighton and into 11th, while Chris Hughton's side fall to 13th and are now five games without a win.
