Drink readily available after close of innings (6)
I believe the answer is:
shandy
'drink' is the definition.
(shandy is a kind of drink)
'readily available after close of innings' is the wordplay.
'readily available' becomes 'handy'.
'after' is a charade indicator (letters next to each other).
'close of' says to take the final letters (the letter which ends or closes the word).
The last letter of 'innings' is 's'.
'handy' put after 's' is 'SHANDY'.
(Other definitions for shandy that I've seen before include "Weakly-alcoholic drink" , "Beer-lemonade mix" , "Light beer" , "Beer and lemonade mixture" , "Beer and lemonade mix" .)
