Jack Brown will make his Anglian League first team debut on Sunday when the teenager competes for Northamptonshire against Leicestershire at Luffenham Heath GC.
The Brampton Heath member joins club-mate Fraser Carnihan, Paul Hodgkiss (Farthingstone), Graham Bott (Cold Ashby), Michael Campbell (Kettering) and Lewis White (Northampton).
With also Wellingborough duo Ryan Evans and Kyson Lloyd playing, the county will be hoping to make a positive start to their campaign after just missing out 12 months ago.
New second team captain Richard Dalton has selected a strong side for the reverse fixture as the county begin their attempt to make it a hat-trick of tournament victories at Whittlebury Park GC.
Dalton plays alongside Overstone team-mates James Barker and Tom Anderson, Bob Clayton (Cold Ashby) and county strokeplay champion Miles Mudge (Staverton).
Dan Ashcroft (Northants County), Matt Hodgkiss (Farthingstone) and debutante Tom Burgh (Peterborough Milton) complete the line-up for the double defending champions.
