Alex Nicholls' goal just before half-time proved to be enough to give Barnet three precious points from a 1-0 win against Forest Green Rovers.In the opening minute Shaquile Coulthirst forced Bradley Collins into a good save and the rebound was deflected behind for a corner.At the other end, Dayle Grubb's shot was headed behind by Michael Nelson and Haydn Hollis headed the corner over from close range.Rovers keeper Collins was called into action again as David Tutonda found space on the edge of the area to shoot.The teams looked to be heading into the break level but Nicholls' low shot into the bottom corner put the home side ahead with virtually the last kick of the first half.In the 89th minute a looping cross was headed down by Christian Doidge towards the bottom corner but Craig Ross pulled off a good save to keep a clean sheet.The win lifts Barnet off the foot of the League Two table and keeps their faint hopes of staying in the Football League alive with four games to go.
