Red Rewind: City so close to Wembley
Martin Foyle is so close to leading the Minstermen to the national stadium for only the second time in their history following a 2-0 triumph at the Bucks Head.
His side began impressively enough with striker Daniel McBreen drilling narrowly wide and busy midfielder Simon Rusk seeing a further effort blocked at the near post.
However, from the resultant tenth-minute corner they made the vital breakthrough, as Rusk swapped passes with youngster Andy McWilliams and despatched an angled drive inside goalkeeper Ryan Young's near post.
Five minutes later Aussie marksman McBreen helped on Purkiss' long throw and Richard Brodie headed wide from only six-yards.
The visitors continued to seriously challenge custodian Young, with first Adam Boyes and then Brodie producing distance attempts, while Jon Adams' overhit free-kick was only a threat at the other end after catching the wind.
A wayward pass by United defender Gavin Cowan soon after the interval then offered Brodie another opportunity, until stumbling and allowing Indy Khela to perform a recovering tackle.
Adams at least witnessed a decent reply capably dealt with by Michael Ingham, before Mark Robinson's clearance struck Luke Moore and flashed only marginally wide of his own goal.
Manager Foyle reacted by sending on the ever-dependable David McGurk for Boyes and reverting to three at the back, with width defenders Purkiss and Robinson pushed into more advanced roles.
He could have been rewarded when Rusk's strong break ended with Brodie's shot being parried by Young and McBreen lifting the rebound over an inviting net.
But York still doubled their tally as Robinson's throw travelled via both McBreen and second substitute Onome Sodje for the oncoming Purkiss to calmly side-foot into Young's bottom left-hand corner.
Moore responded too high from the edge of the area before having an effort disallowed when Ingham appeared to lose control of Martin Naylor's long throw.
Ingham was also called into action by Andy Brown after Robinson already had another strike cleared off the line by home defender Stuart Whitehead, while both McBreen and Sodje spurned later chances as the visitors attempted to strengthen their hold.
