Some well known current and former Pembrokeshire cricketers are likely to be involved including Simon Cole (Cresselly), Dave Lee (Whitland), Andrew Williams (St Ishmaels) and Huw Evans the former Cresselly wicket-keeper batsman who is now playing at Ammanford.
The officers are based in various parts of the Dyfed Powys police area.
One of the umpires will be Dave Morris, a retired police officer and well known former Cresselly and Dinas all-rounder, who is a past chairman of Pembroke County Cricket Club.
