Wrexham picked up ground on Vanarama National League leaders Notts County following a 1-0 victory over Maidenhead United at the Racecourse Ground.
Aaron Hayden scored his eighth goal of the season, heading home after half an hour.
It could have been two for the Dragons, but Paul Mullin missed a late penalty. Wrexham did hang on for a fourth win in five games.
Phil Parkinson's men are one point behind Notts County while Maidenhead are 16th following a third defeat in their last four.
Story of the match
Parkinson made two changes from the side that defeated Altrincham on the weekend as Bryce Hosannah came in at left wing for Callum McFadzean and Elliot Lee replaced Jordan Davies.
The Dragons had an early chance as a ball into the area was taken down by Ollie Palmer and he laid it off to James Jones, who saw his shot saved by Alexis Andre.
Andre then saved from Mullin and Lee played a neat one-two with Palmer and he saw his strike deflected behind for a corner, which came to nothing.
Palmer and Jones then combined before Hosannah sent in a cross that Mullin wasted by shooting into the side netting.
Following a corner from Luke Young, Maidenhead survived during the goalmouth scramble.
On 30 minutes, the Dragons found the goal they were looking for. Another corner by Young found the head of Hayden, who calmly beat Andre.
The hosts got into decent positions but were unable to come up with anything as they held a one-goal lead going into halftime.
Charlee Adams had a good chance for the Magpies, but his long-range effort flew over the bar.
In the 55th minute, another corner by Young saw Hayden's flick stopped by Andre and the rebound kneed onto the roof of the net.
The Dragons kept creating chances, Anthony Forde's low drive just going wide and Mullin got onto the end of his cross, but it was deflected over the bar. Jones then fired over after a partial clearance.
On 71 minutes, Wrexham were forced into a change as Jordan Tunnicliffe limped off and was replaced by Tom O'Connor.
It should have been two as a goalbound header by Hayden was cleared and Andre came up with a brilliant save to deny Ben Tozer before palming the rebound away.
Mullin was brought down in the box by Will de Havilland and referee pointed to the spot, but the Dragons' talisman was unable to convert.
Davies come on for Lee with five minutes to go and Andre made three brilliant saves, first stopping Mullin then denying Jones and finally tipping Davies' fierce drive around the bar.
Player of the match: Alexis Andre (Maidenhead United)
