BLUES' Championship charge is still on course after they recorded a seventh victory on the spin when they overcame mid-table Carlton Town at Harrison Park on Saturday.
Leek won by the only goal but they missed enough glorious chances in the second half to have won by a much higher score-line.
The game proved to be a stop-go affair as play was interrupted on a regular basis by the assistant referees' flags mainly for questionable off-side decisions.
Leek manager Lee Casswell said: "I think at this stage of the season getting the three points is important as our pitch is a real leveller.
"The victory should have been more emphatic when you look at all the chances we created especially in the second half.
"As our challengers for the title keep winning we'll just carry on doing things our way taking the proverbial one game at a time as the players continue to achieve the targets we have set them," he added.
Casswell went into the game making three changes with Rhys Swetnam given the nod to cover for the unavailable Karl Espley whilst Tim Grice and Niall MaGuire missed out in favour of Dan Shelley and Sam Hall.
Leek were celebrating the lead in the fifth minute when Johnson found the net following a good move down the right but the elation was short-lived as the effort was ruled out by the off-side flag.
Carlton's Kallum Keane was cautioned for a shocking challenge on Anthony Danylyk.
Hall bravely blocked a shot from Daniel Elliott who missed out again with a shot wide of the upright before Leek got the break-through in the 33rd minute. Blues built a good move down the right before John Johnston drove a low cross into the box and Jordan Johnson drilled the ball into the back of the net.
Carlton came close to drawing level just before the break when Ben Chapman pulled off a great save to deny Alex Troke from a free kick on the edge of the box.
Carlton rarely figured during the second half and in the 65th minute Leek came close again putting another good move together before John Johnston curled a shot narrowly wide of the post. Carlton pushed forward in the final 10 minutes but failed to get a shot on target whilst John Johnston should have doubled the score when he capitalised on a mistake by Viscosi but, with the goal at his mercy, his shot lacked power and a defender recovered to clear the ball off the line.
