Hallam fightback
Hallam trailed a Richard Metcalf first half hat-trick and when Gary Hepples extended the lead two minutes after the interval after appearing to kick the ball out of Martin Taylor's hands, the Blues looked to be heading for a hiding.
Phil Reynolds reduced the arrears with a speculative long range effort which seemed no more than a consolation effort.
But Geelan's men had other ideas and five minutes later recent signing Jordan Turner pulled another one back with a fine finish inside the box.
A minute later central defender Lee Cooksey tapped home from close range to make it 4-3 after the Scarborough keeper had missed a cross into the box.
The home side were visibly rattled as Hallam equalised with almost the last kick of the game when Jordan got in beyond the defence to steer a shot wide of the keeper. While it wasn't enough to lift the Sandygate Road club out of the bottom two, it did put them to within three points of safety with two games in hand and will no doubt put them in good heart ahead of tomorrow's derby at Armthorpe Welfare.
