Jim Hamilton felt Scotland's good work in the scrum paved the way for their 12-8 Six Nations victory over Ireland at Murrayfield on Sunday.
Although the visitors nabbed the only try of the game through Craig Gilroy, scrum-half Greg Laidlaw's four penalties for Scotland proved decisive.
And lock Hamilton said: "We have put a lot of work into our line-out and scrum. I thought our scrum was absolutely immense.
"I think a special mention has to go to Geoff Cross. He has come in and done a magnificent job. Credit to all the forwards.
"We really dug deep today and I think you can see that win means a lot to us.
"We knew Ireland notoriously start well, so we hung in there in the first half.
"To go in at half-time with the score at 3-0 to Ireland was probably a good outcome for us.
"We went out in the second half and had to dig deep, and we took our chances."
