THE Motormen were taken to finishing school on Saturday as Alfreton punished a distinct lack of composure in front of goal.
From a position of total dominance in the opening half hour, Carl Macauley's men slid to a disappointing defeat on a glue-pot of a pitch in Derbyshire.
Missed chances and goals conceded from set-pieces contributed to a disappointing afternoon for Vauxhall, whose run of games without a win now extends to six.
From the first whistle, Motors took control and, on nine minutes, Anthony Wright played a perfect through ball for Thomas Rooney only for his shot to come back off the post. Seven minutes later, home keeper Dale Roberts made a terrific save to keep out a strong shot from Tom Field and, shortly after, Roberts distinguished himself again, this time from the head of Joe McMahon.
Alfreton's first serious threat came on 28 minutes when Tristram Whitman blazed well over after a neat build-up on the left before Mark Rawle saw his header saved by Sean Lake from a corner.
As half-time approached, the Reds grew in confidence and, just before the interval, struck a killer blow.
An Ashley Burberry corner was headed clear by Brian Moogan at the near post but only as far as Ryan Clarke, who volleyed home from just outside the area.
After the break, Motors piled on the pressure but could not take their chances. Alfreton then twice went close through Rawle, his second effort cannoning off the frame of the goal.
On 74 minutes, Vauxhall keeper Lake made a great save from a deflected Burberry shot. From the resultant corner, Rawle was left unmarked in the box to head the hosts further ahead.
Motors tried to fight back with two free kicks but this was one occasion when even they were unable to stage one of their trademark comebacks to salvage a point.
Motors boss Macauley said: 'In the first half, we played well and were in control of the game really. But when you miss as many chances as we did then you get punished. We missed three one-on-ones with the keeper and that's just not good enough.
'We got punished as we conceded two goals from set pieces. The second half was unacceptable.'
