Red Rewind: Majestic York produce cup shock
The Minstermen produced an absolutely heroic rearguard display and with a couple of very late goals finally accounted for their higher-ranked opponents 3-1 following a truly dramatic conclusion at the Madejski Stadium.
Former Northern Ireland international centre-back Darren Patterson was earlier handed a full debut for the visitors, and went on to provide solid leadership and organisational skills from within their regularly tested defensive line.
But City were still to fall behind midway through the opening half as Keith Jones crossed from the right for ex-Tottenham Hotspur midfielder Darren Caskey to locate the back of their net from around ten-yards.
Courageously they were back level just five minutes later, when midfielder Steve Agnew produced an unstoppable volley from the edge of the area after Graham Potter had swung in an only partially cleared free-kick.
However, York were also indebted to defensive rock Mark Sertori making a couple of goal-saving challenges and also scrambling the ball off the line.
Meanwhile, highly-rated international goalkeeper Alan Fettis produced a number of fine saves, and when he was beaten again by Jones just before the break, the effort was ruled out for an assumed handball.
The inspirational Fettis had already crucially blocked while faced with only the advancing Martin Butler, therefore allowing the recovering Patterson to clear from the line.
He also proceeded to keep out efforts from Jones, Butler and Ricky Newman, and a brace of challenging volleys by Phil Parkinson and Lee Hodges.
Opposite number, Halifax-born Phil Whitehead, had in contrast been largely inactive, despite Alex Mathie wasting a very early opportunity and later sending a further attempt directly at him.
But with just a couple of minutes remaining, York broke away as the offside flag controversially remained unemployed, and on loan Stoke City striker Chris Iwelumo unselfishly allowed substitute Colin Alcide to slot into the net.
And as the contest then moved into added time, Iwelumo defiantly chased onto Mathie's forward delivery, and with keeper Whitehead venturing towards the corner of the box in an attempt to clear, the ball instead ricocheted goalwards and rolled slowly and agonisingly across his line.
