A new International Cricket Council ruling means Scotland could also include Yorkshire all-rounder Gavin Hamilton if he does not make England's final 15. He is currently playing in Australian Grades cricket.
The preliminary squad contains a blend of experience and youth. Old stagers Iain Philip and Bruce Patterson are joined by youngsters who featured in last year's under-19s World Cup in South Africa such as Fraser Watts, Greg Butchart, Martin Hay, Gregor Maiden and Craig McKellar, the latter perhaps the biggest surprise choice.
SCOTLAND SQUAD: C Smith, M Smith, K Thomson (Aberdeenshire), A Keith, I Stanger, J Williamson (Clydesdale), P Steindl, S Crawley, G Salmond (Grange), R Parsons, A Tennant, M Hay (Prestwick), M Allingham, A Butt (Heriot's), D Cowan, S Gourlay (Freuchie), G Maiden, C Wright (West of Scotland), B Lockie, D Watts (Carlton), J Blain (Northants), G Butchart (Dunfermline), A Davies (West Lothian), N Dyer (Edinburgh Accies), D Lockhart (Glasgow Accies), C Mackellar (RHSM), I Philip (Stenhousemuir), B Patterson (Ayr), K Sheridan (Poloc), J Brinkley (Hants).
