Ospreys hooker Dewi Lake will lead Wales U20s for the first time against Italy this weekend.
Both captain Tommy Reffell and Tom Hoppe suffered injuries in Sunday's defeat to France in the opening game of the championship while second row Jac Price is unavailable for selection after picking up a suspension for a dangerous tackle. Ospreys hooker Dewi Lake takes over the captaincy for the first time in Reffell’s absence.
Fellow regional team mate Rhys Davies packs down alongside Lake, with Cai Evans getting the nod at fly-half to complete the Ospreys contingent in the lineup.
"We've been keen to keep an element of consistency to our squad, but some changes have been forced upon us with Tommy Reffel's injury and Jac Price's suspension," said Williams.
"It was a great measure of where we are last week against the world champions, and the challenge for us this week is to replicate the intensity we mustered for 60 minutes against France.
" There are certain scenarios we need to control more effectively, and Italy will be a confident group following an excellent performance and result against Scotland.
"We remember our loss last year at home, and know the challenges keep coming in this Six Nations.
"It is our ambition to keep improving our processes. There were aspects we were very happy with on the weekend, and certain areas we need to increase our efficiency.
"Dewi Lake will be an excellent captain in what will be his first outing with this honour. He and fly half Cai Evans have acted as key leaders in our early preparation and for the first game against France."
