Northern Ireland go second

However the win came at a price with key trio Kyle Lafferty, Steven Davis and Grant McCann all booked and ruled out of the crucial home fixture against Poland next month.

That was the only downside on a good night for the province and a special one for Gareth McAuley and Chris Brunt, who both scored their first goals at this level. Grant McCann was also on target as they moved into second place in Group Three on goal difference, although they have played a game more than their rivals.

Northern Ireland took the lead in the seventh minute and never let go of their grip on the game against a side that has never won a competitive game. McAuley smashed a superb half volley into the net following a corner from McCann.

Stephen Craigan should have added a second in the 13th minute when he got clear of his marker when McCann delivered the corner only to scuff his effort wide of the target.

Northern Ireland kept up the momentum and Lafferty cracked in a shot in the 22nd minute that was blocked. But they did not have long to wait before extending their lead.

It was another fine strike as well with McCann rifling a shot into the corner from 18 yards after Martin Paterson's effort was blocked in the 32nd minute.

McCann almost added a third goal for Northern Ireland after the break, his inswinging free-kick hitting the top of the bar.

Substitute Brunt made an immediate impact and put the province 3-0 ahead in the 63rd minute, driving in a a 25-yard free kick that went under the hapless goalkeeper's body.

San Marino were reduced to 10 men in the 70th minute when Manuel Marani was sent off after picking up a second yellow card.
