Slugger's need (3)
I believe the answer is:
bat
'slugger's need' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for bat that I've seen before include "Flutter (eyelids)" , "Cricket, table-tennis and baseball implement" , "Nocturnal flier" , "Night-flyer" , "Club used in cricket" .)
