Leading batsman’s gadget for accessing the booze? (6)
I believe the answer is:
opener
'leading batsman's' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for opener that I've seen before include "First event in a series" , "initial goal" , "No.1 or No.2 bat" , "man, first at the crease?" , "cricketer, first at the crease?" .)
