As the clock ticked into additional time, the home side doubled their lead.

Zack Kotwica was introduced by Mark Yates to give the squad a more attacking dimension.
Their chance's kept on coming, Doyle shot into the side netting and Roberts shot wide as the game entered the final 10 minutes.
O'Shea had the crowd on their feet as his right footed shot bends away from goal. Was again involved, beating Brown and Elliott in the Robins box only to be denied by the chest of Scott Brown.
Darwika's neat one-two with Doyle earnt enough space in the box to force an excellent save by the advancing Scott Brown.
However, their willingness to commit players forward often left the Robins exposed defensively.
The Robins were able to commit men forward, and looked threatening in attack even if unable to create a clear cut chance.
Byron Harrison came close for the visiting Robins as he beat several defenders in the Spireites 18-yard box. His jinking run ultimately denied by the on-rushing Tommy Lee as a last resort.
However, Troy Brown's header was ruled out for off side as it passed the stranded Tommy Lee and ruffled the netting.
Cheltenham had the ball in the net shortly after, and the game sparked into life.
Terry Gornell was replaced by Ashley Vincent seven minutes after the restart, the striker went down in the centre circle of his own accord.

Roberts' direct free kick tested Brown in the closing stages of the half but the ever present shot stopper parried his effort away from goal with relative ease.

Â
With Richards, Smith and Talbot all creating plenty of opportunities in and around the box, Chesterfield failed create any further meaningful chances before half-time.

The home side had started the brighter and took the through Gary Roberts.
Shortly after the winger's curling effort from range dropped just wide of Lee's left hand upright.
