Match ends, Bolton Wanderers 1, Huddersfield Town 0.
Craig Davies's fifth goal of the season secured victory for Bolton and moved them above opponents Huddersfield in the Championship.
The home side, unbeaten at home under Neil Lennon, struck in the second half when Davies scored from close range.
Goalkeeper Andy Lonergan twice made crucial saves for Bolton, denying Nahki Wells and Jacob Butterfield either side of half-time.
Bolton move up to 18th, with Huddersfield dropping to 19th.
The away side had settled into the game quicker but struggled to make an impression in the final third.
But with Davies in their side, Bolton were always a threat and the striker posed a constant menace to the Huddersfield defence.
He drew a clumsy challenge out of Mark Hudson right on the edge of the area, but the free-kick came to nothing, before seeing a long-range strike saved by Huddersfield goalkeeper Alex Smithies.
Just before the break, though, Wells forced Lonergan into a fine save and then sent a shot just wide as Huddersfield finished the half on top.
They continued to enjoy the better of the play at the start of the second period, with Lonergan again called upon to deny Butterfield from close range.
Grant Holt poked just wide for Huddersfield before Davies ensured the three points went Bolton's way when he fired home from eight yards after the hour.
Bolton manager Neil Lennon:
"It was a huge win and as the game wore on we got stronger and better.
"When you are trying to be consistent and trying to win things, you need your goalkeeper. I had a great one at Celtic [Fraser Forster] and Peter Schmeichel did it for years at Manchester United.
"I hope Andy [Lonergan] continues in the same form. All good teams have great goalkeepers. I am not saying Andy is great by any means but he has been excellent since I came in."
Huddersfield manager Chris Powell:
"I have a disappointed changing room because we were very much in the game.
"It's a game you look to take something from because of the position of both teams.
"We knew Bolton had an uplift in form since Neil came in but we felt comfortable coming here and playing the way we did. The chances were there for us to take something.
"I think a draw would have reflected the whole game."
