Mathias Pogba scored twice as Blue Square Bet Premier leaders Wrexham completed a double over Lincoln City with victory at the Racecourse Ground.
The home side went ahead on 11 minutes when Pogba's 20-yard shot was deflected past visiting keeper Paul Farman.
Wrexham then doubled their lead from a disputed penalty after Andy Morrell's shot was handled by John Nutter.
Pogba stepped up to take the 61st minute spot-kick, sending Farman the wrong way to secure Wrexham's victory.
Lincoln failed to trouble keeper Joslain Mayebi as Wrexham secured their eighth win in 12 games under player-manager Morrell.
Victory was enough to keep Wrexham on top, but only on goal difference from Fleetwood, who beat Stockport County 2-1 in the day's late kick-off.
VIEWS FROM THE DRESSING ROOM
Wrexham player-manager Andy Morrell told BBC Radio Wales:
"They started well, which we said they would. We were able to get through that period and then we scored, against the run of play a little bit.
"But then I thought we took control and well merited the three points.
"I'm not going to single anybody out because I thought everybody did great."
Imps manager David Holdsworth told BBC Lincolnshire:
"We're going home empty-handed, which is disappointing. In the first half you would not have recognised which side were the league leaders and which side were supposedly struggling so there are a lot of positives in the way the boys applied themselves.
"Their first goal took a deflection off Mitch Nelson's foot when Paul had it covered, so that little thing turned into a big thing because at that point we were on top and the league leaders weren't giving us any problems.
"For the penalty the linesman was three yards away, the referee 63 yards away, with players between him and the ball. It was an incredible decision and a game-changing decision because, at 1-0, we were well in the game."
