Lynton Wilkinson took the Sphinx side and like Danny McSheffrey at Oldbury on Wednesday night, saw his team fall behind when David Fisher scored in the 15th minute.
It was not until the last quarter of the second half that Sphinx came back at Oadby and they levelled through Dave Freeman, who had opened his Sphinx first team account on Wednesday in the 75th minute.
Three minutes later, Tom Thacker fired Sphinx into the lead and in the last minute, Freeman scored again.
