Into the second half and County enjoy spells of possession in the hosts half. Scott Barrow delivered a tricky corner, that 'keeper Emililano Martinez caught at the second time of asking.
The hosts took the lead from a penalty, conceded by Scott Barrow after a challenge in the area that looked dubious. Benik Afobe stepped up and dispatched the penalty to the right of Joe Day.
