WREXHAM made it two home wins in the space of four days with a hard-fought 1-0 victory over Lincoln City in League One.
James McClean's shot in the second half which went in off a Lincoln defender proved to be the difference between the sides as Phil Parkinson's men remain second in the table and unbeaten at The Racecourse.
The Reds didn't play as well as they did in Saturday's 3-0 success against Exeter City but the result is all that matters.
Wrexham, without a game this weekend, remain four points behind leaders Wycombe Wanderers.
After his side produced a superb display against Exeter, Parkinson named an unchanged side against Lincoln.
Wrexham saw a lot of the ball in the early exchanges and George Dobson headed wide from McClean's cross.
Lincoln came more into the game and Reds' goalkeeper Callum Burton made a brilliant reflex save to keep out Paudie O'Connor's header from Sean Roughan's free-kick.
Another Imps set-piece caused problems with Bailey Cadmarteri putting his effort wide.
Wrexham came back into it and Ollie Palmer went down under Erik Ring's challenge in the area but no penalty was given.
Lincoln had the upper hand and a low free-kick into the area was deflected just over the bar by a Wrexham player.
There was a sight of goal for Wrexham when McClean, who found himself in a central position, crossed to the back-post but Palmer's shot went across goal.
Jack Moylan fired wide on the turn for Lincoln and there was an even better chance for Wrexham when Lewis Brunt's header struck the top of the crossbar from McClean's free-kick just before the break.
Palmer's header from Dobson's cross was saved by keeper George Wickens with the first opportunity of the second half but it was a subdued performance by the Reds.
It got better as Palmer took a cross down and fired over and Wrexham took the lead in the 67th minute.
Dobson picked out McClean in the area and his shot found the back of the net off defender Tendayi Darikwa.
Palmer headed straight at Wickens from Barnett's cross but Lincoln weren't out of it.
Jack Moylan and Jovon Makama both went close while Rob Street wasn't far away in added time before Barnett shot wide for Wrexham and one goal proved to be enough.
