HARRIERS boss John Eustace praised the way his players persevered against determined Boston United.
Reds picked up a hard-fought 1-0 win thanks to Elton Ngwatala's 87th minute header.
Kidderminster struggled to break down their well-drilled opponents for long spells but finally struck to leave their promotion push well on track.
It also saw them hit back after Tuesday night's set-back at Stalybridge Celtic.
Eustace said: "I'm delighted. The lads really stuck to the task well against a really good Boston team so I'm delighted to get the goal in the end.
"It was difficult for us at times but I couldn't be more pleased with the way the lads kept at it and I think we got what we deserved in the end.
"I said from day one that we're only worried about ourselves. We haven't looked at any other results. The most important thing was to get a reaction after Tuesday night, which we did.
"We've got a very tough game on Monday now so we have to prepare properly for that.
"I've said all season that it's a squad game and the lads coming in and coming off the bench made a difference today."
