TWO second-half goals ended Gresley's mini-revival and Scarborough were only denied a more emphatic win by the excellence of Mats Morch.
It might have been different had John Guy's fourth-minute effort not rebounded out off the underside of the bar.
At the other end, keeper Morch, on loan from Derby County, produced a string of fine saves to deny Ryan Williams, Grant Ryan and Jordan Thewlis.
But there was little he could do to keep out Andrew Milne's 57th-minute header.
Gresley almost levelled when Kieran O'Connell's shot hit the inside of the post before rebounding straight into the hands of keeper Jason White.
Morch reacted quickly to save Ryan Blott's close-range effort – but the visitors sealed the win in the 75th minute, Thewlis capitalising on a slip from Jamie Barrett to score via the far post.
