Scotland U20 head coach Sean Lineen has made just one change to the side which lost to France in Round 4 for their season finale against Wales at Stadiwm Zip World, Colbyn Bay this evening.
Jack Hill joins the back-row on the blindside, replacing Gregor Brown who takes a seat on the bench.
Both Wales and Scotland achieved their first wins of the tournament in Round 3, the former going on to be victorious in Round 4 as well.
Lineen said: "We are looking to finish the tournament on a high this weekend.
"The players are very determined and focused on the task at hand and I've been really impressed with the players' attitude and mindset throughout the tournament.
"They've continually looked to improve their game each week and hopefully they'll be rewarded for their efforts this Friday.” Lineen said.
Wales have made two changes for the clash, in the forwards, Scarlets hooker Dom Booth replaces Will Griffiths.
Amongst the backs, Ioan Lloyd is preferred to Jacob Beetham in the 15 jersey.
Wales will be in search of their third win of the tournament.
"It will be good to finish the competition with that momentum but we know how difficult the challenge against Scotland will be." Head Coach Gareth Williams said.
