Wrexham were held to a goalless draw under the Racecourse floodlights by fellow high-flyers FC Halifax Town.
Mike Fondop hit the bar early on for the Dragons, while the Shaymen had a goal ruled out at the other end but neither side could break the deadlock in an even contest.
After leapfrogging the Shaymen with Saturday’s 2-0 home win against Aldershot, the league leaders made four changes including a debut for Jake Lawlor and a return for fit-again James Jennings.
Doug Tharme and Kevin Roberts made way in defence, while Paul Rutherford and Rekeil Pyke also returned in place of Nicky Deverdics and Stuart Beavon.
The Dragons were inches away from the perfect start – Mike Fondop’s brilliant, dipping left-footed shot from distance clattering the bar just four minutes in
Halifax had the ball in the net on eight minutes, when Matty Brown headed in from a vicious Matty Kosylo corner, but the goal was ruled out for an infringement.
The Shaymen responded well though and Kosylo got in down the left after a loose Akil Wright pass and pulled back for Jonathan Edwards on 13 minutes but he curled over.
A minute later, Dayle Southwell tried his luck from distance but he too sent his shot high and into the Kop.
Wrexham grew into the game, however, and Jennings’ long-range shot was blocked on 18 minutes before Wright shot wide from the rebound.
Fondop was in the thick of the action too and he did well to chest down Jordan Maguire-Drew’s cross on 28 minutes but he volleyed over left-footed.
A minute later, Wrexham’s top scorer rose highest to meet Maguire-Drew’s free-kick but his looping header was saved and held.
Halifax remained especially dangerous from set pieces, however, and Clarke got up again from James Berrett’s corner on 36 minutes but Luke Summerfield cleared off the line.
Fondop’s aerial prowess showed again at the start of the second-half, twice heading over from Maguire-Drew’s crosses inside the first ten minutes.
Jennings then crossed for Pyke on 56 minutes, but his glancing header lacked power and was saved.
With still no goals 20 minutes into the half, however, Ricketts shuffled the front three as Beavon replaced Fondop and Pyke moved into the central striking role.
At the other end, Edwards cut inside from the left but his low right-footed shot was saved and held by Lainton at his front post on 67 minutes.
Wrexham’s second change saw Luke Young on for the final 20 minutes in place of Rutherford, while Chris Holroyd replaced Maguire-Drew in the 81st minute.
But, while they enjoyed more attacking possession, the Dragons’ balls into the box were met by a wall of defenders in lime green.
And the visitors nearly snatched all three points against the run of play in the 89th minute when Southwell’s low shot flashed just wide across goal via a slight deflection.
Beavon then could have won it for Wrexham in stoppage time, but he shot over when Holroyd’s deflected effort fell to him in the area.
Neither side could make a breakthrough, however, leaving Wrexham one point clear of the Shaymen despite dropping to third.
