Scottish Thistles, a development team, for Scotland 7s finished the opening leg of the 2014 GB7s Series in second place.
After completing their group with a perfect three results, they lost out to Samurai in the final, 21-0.
Their pool results were 31-5 v Crawshays Welsh first up, before beating the Wailers 21-10 and then completing the group v The Army, 33-17.
In the semi-final they beat England IPF 21-14 before their final v Samurai.
Head coach, Graham Shiel, said: “The team were very good today and it has been a very positive outing.
We were a solid side throughout the day and we performed at a high level. The Army were tough and we showed inexperience, but our intensity and defence caused the opposition problems and we came out on top.
“We took our opportunities when they came and moved fast in attack. We will take a lot of confidence from today.
“England IPF were a tidy outfit with lots of pace, but we defended well and played a clever game against them. Samurai were simply better in the final; they stopped us from playing and retained possession.
“It was a long day and they were the better side.”
Scottish Thistles go into next weekend’s tournament in Edinburgh (Boroughmuir RFC, Meggetland on Saturday 31 May) with 20 points. Samurai lead the standings with 21 and England IPF has 19 in third place.
