Joshua Jamieson in line-up for Wales clash
The 17-year-old, who posted a five-under par aggregate of 283 at Nairn Dunbar to take the boys' title by three shots, is one of two St Andrews golfers in the team, with Ewan Scott also included.
Four other members of the team who finished second behind Ireland 12 months ago - Grant Forrest, Liam Johnston, Jack McDonald and Daniel Hendry - retain their places, hoping to build on a positive performance when they defeated England for the first time in 13 years.
Current leader of the SGU Boys' Order of Merit Greig Marchbank makes the side, along with Junior Champion of Champions winner Craig Ross and rising Lothians star Anthony Blaney. Blairgowrie's Bradley Neil, runner-up in the English Boys Under-16s Championship, earns a call up, as does Mount Ellen's Eamon Bradley, who performed well for Scotland in the European Boys Team Championship.
Scotland Boys team: Anthony Blaney (Liberton), Eamon Bradley (Mount Ellen), Grant Forrest (Craigielaw), Daniel Hendry (UAE), Josh Jamieson (St Andrews New), Liam Johnston (Dumfries & County), Jack McDonald (Kilmarnock Barassie), Greig Marchbank (Dumfries & County), Bradley Neil (Blairgowrie), Craig Ross (Kirkhill), Ewan Scott (St Andrews).
