Reece Hackett scored his first league goal since the opening day as Lincoln made it three home wins in a row with a 1-0 victory against struggling Port Vale.
The League One basement boys have lost five games in a row and rarely threatened the promotion-chasing hosts at Sincil Bank.
Michael Skubala’s Imps started brightly but struggled to create any big chances.
Vale’s best chance of the game fell to Ronan Curtis when he headed wide.
They came close to breaking the deadlock on the half-hour mark when Ben House’s effort was cleared off the line by Ben Heneghan.
It was a special strike to open the scoring as Hackett fired home from the edge of the box in the 33rd minute.
It was a scrappy second half as neither side went close to scoring.
Vale huffed and puffed without reward as Lincoln held on for all three points to maintain pace in the promotion race.
