After the sides had drawn 0-0 at York on Saturday, the first half of Tuesday night's replay at freezing Field Mill was a dire affair with the home fans again booing their side off after seeing little to warm them.

• Stags through, but boo boys again upset McEwan

But after 141 minutes of deadlock, the tie was finally opened up on 51 minutes by Somner's low shot, his second goal for the club in a much improved second half showing by the Stags.

It was the first time this season Billy McEwan's men have managed back to back clean sheets but, more crucially, it earned them the big prize of a trip to Saltergate the weekend after next and lifted spirits after five games without a win.

Stags showed two changes from Saturday's first encounter with Alan O'Hare under the weather with illness again and Michael Blackwood missing out with the ankle injury that forced him off on Saturday.

Frenchman Chanot replaced O'Hare in defence while Hurren came into the midfield in a 4-3-3 formation.

York lost Craig Farrell through injury too so former Leeds trainee Rothery made his debut in midfield.

Russell volleyed well over from just outside the box as Stags tried to clear and early City free kick.

A McGurk error gave Stags an unnecessary corner on four minutes which Jeannin swung in dangerously and Ingham rose to clutch safely.

Stags survived two York corners and a scare when Chanot was almost caught dallying on the ball by McBreen. Jeannin had to hook a bouncing ball away from in front of goal to concede a third corner after Wilkinson had flicked in in from the by-line.

Jeannin headed the flag kick clear but when the ball was put back in there was an unsuccessful penalty shout for handball against Chanot.

On 28 minutes Rothery tried from 30 yards and wasn't too far over the angle - the best effort so far in a drab replay.

The game was so poor that there were ironic jeers from the home fans a minute from the break when Arnold rifled Mansfield's first shot in anger just wide of Ingham's right hand post from 25 yards.

Soon after the half time whistle was greeted by boos from the home fans at the end of one of the worst 45 minutes seen at Field Mill this season. But all that was to change dramatically.

O'Connor replaced Sinclair for the second half and almost found a breakthrough within four minutes as he headed over from six yards after battling to get on the end of a long Hurren throw from the right.

Hurren then had a low shot blocked. But Stags finally produced the big breakthrough on 51 minutes.

Arnold laid a neat ball to his right on the edge of the 18 yard box and Somner stroked a low finish inside Ingham's near post.

The Minstermen immediately sent on danger man Sodje and soon won a corner which was cleared at the second attempt.

Arnold tried to set up Hurren from 25 yards but the referee got in the way and Hurren eventually screwed his finish wide. D'Laryea also tried one from distance but Ingham was well placed.

At this stage there was uproar in the away end as troubled flared between York fans and stewards.

The shoot on sight policy continued as Hurren was again wide of the right upright from 20 yards after superb work from Lee out on the left.

Boyes replaced McBreen on 63 minutes and within two minutes was booked for a challenge on Chanot.

Still Stags threatened and Lee cut inside from the right of the box to fire narrowly wide.

McGurk was also cautioned on 67 minutes for a cynical trip on Arnold as he tried to go it alone at the York defence.

Boyes had an ambitious swing from long range which was always going wide though Wilkinson tried to get a touch en route which could have caused Gamble problems if he had managed to divert it on target.

Sodje then sliced a hurried shot well wide to huge jeers with 17 minutes to play.

But Sodje should have levelled on 78 minutes. Robinson fired a first time shot into the which shot up into the air in front of goal where Sodje somehow missed the target with a header from point blank range.

Robinson was well over for the increasingly desperate visitors from distance and soon after Gamble dropped well onto a dangerous Boyes cross.

A City corner two minutes from time shot straight across the face of goal.

But in the last minute Stags broke down the right through Silk who sent O'Connor forward. His perfect low cross for Arnold in space seven yards from goal left the youngster looking a certain scorer but the keeper denied him with his feet.

Four tense minutes were added on and O'Connor headed straight for the corner were the referee strangely penalised him for shielding it.

But the young striker intelligently continued to do the same and frustrate the visitors.

Arnold came so close again in stoppage time as he beat Purkiss to the ball and then lobbed the keeper only to see the ball bounce wide of the far post with the goal gaping.

Stags survived a late, late scramble in their box and hung on for glory.
