Duns just missed out on promotion to the East of Scotland Premier Division by a point at the weekend.
The Dingers did what they had to do, beating Ormiston after a midweek victory over Peebles.
But in the end it was just not enough, as Heriot Watt pipped Eyemouth United 3-2 to clinch runners-up spot in the First Division behind champions Peebles.
Tansey was forced into making a good early save as the hosts went on the offensive, but Duns hit them on the counter and Stevie shennan had a shot saved by the home keeper.
On 19 minutes Des Chisholm opened the scoring for the Dingers when, after good support play by Shennan, he struck a cracking left footer from 25 yards beating the home keeper.
It took just a further three minutes to double the lead when Mark Weatherburn placed an accurate header just inside the back post after Shennan had brought the ball under control for his second assist.
A few minutes later Shennan was at it again, this time going full length to connect with a header which went narrowly past the right hand upright.
After half an hour Ormiston pulled a goal back when the home striker finished well despite claims for offside from the visitors..
That only spurred Duns on because only two minutes later Michael Robinson curled a shot come cross beyond their keepers left to go 3-1 up.
The home side were not giving up, however, and on the stroke of half time a speculative 40 yard attempt found space just above Tansey’s outstretched arm find the back of the net to make it 3-2 at the break.
Duns were of quicker after the break and created a couple of early chances before Chisholm found the netafter 50 minutes
Ormiston became the more dominant side for a spell, but Duns responded and Lauder went close when he shot wide after a goalmouth scramble.
This was a great effort from Duns, but the closeness of the final table shows that every point counts throughout the season.
