Openers for county's team hitting first sixes (10)
I believe the answer is:
corkscrews
'openers' is the definition.
(corkscrew is a kind of opener)
'county's team hitting first sixes' is the wordplay.
'county's' becomes 'Cork's' (county of Ireland).
'team' becomes 'crew' (crew is a kind of team).
'hitting' is a charade indicator (letters next to each other) (hit can mean to touch on or border).
'first sixes' becomes 's' (1st letter of 'sixes').
'corks'+'crew'+'s'='CORKSCREWS'
'for' is the link.
(Another definition for corkscrews that I've seen is " these'll help those who've got in the drink".)
