Chesterfield 0-2 Huddersfield
Jordan Rhodes grabbed his 34th goal of the season as Huddersfield Town kept up their League One promotion bid with victory over struggling Chesterfield.
The hosts started brightly but Lee Novak's hooked right-foot finish from outside the area put Town ahead.
And Rhodes smashed in Jack Hunt's cross to make it 2-0 at the break.
Gary Roberts also hit the bar and although Chesterfield pushed Huddersfield back in the second half, the visitors were really threatened.
The win sees the Terriers move to within three points of third-placed Sheffield Wednesday, while the bottom-of-the-table Spireites are now six points adrift of safety.
VIEWS FROM THE DRESSING ROOM
Chesterfield manager John Sheridan told BBC Radio Sheffield:
"I thought we started really well and when they get their (opening) goal, I'm really gutted.
"It's just basic things that are costing us. It's just us miskicking the ball. I keep telling them, I don't know how many times I've said it.
"It gives the opposition belief that they can get in the game."
Huddersfield Town manager Simon Grayson told BBC Radio Leeds:
"We've won tonight and we have nine big ones coming up and still a lot of games to be played, lot of points to be won and lost by other teams, and were certainly in the mix come the end of the season.
"We put in a real good team performance with some outstanding individual performances.
"If we win on Saturday we also close the gap of a few other teams as well."
