Nothing gained by rustic cricket shot (not one for purists) (5)
I believe the answer is:
hoick
'cricket shot not one for purists' is the definition.
(unconventional type of cricket shot)
'nothing gained by rustic' is the wordplay.
'nothing' becomes 'O' (looks like zero - 0).
'gained by' indicates putting letters inside (inserted letters are acquired or gained by others).
'rustic' becomes 'hick' (synonyms).
'o' put into 'hick' is 'HOICK'.
(Other definitions for hoick that I've seen before include "Lift sharply" , "Raise suddenly" , "Pull abruptly" , "Tug" , "Rise up" .)
