Racket has wrong tab (3)
I believe the answer is:
bat
'racket' is the definition.
(I know that bat is a type of racket)
'wrong tab' is the wordplay.
'wrong' indicates anagramming the letters.
'tab' anagrammed gives 'BAT'.
'has' acts as a link.
(Other definitions for bat that I've seen before include "Cricket implement or flying mammal" , "Nocturnal animal - racket" , "once wielded by 60 [GREIG]" , "Nocturnal flier" , "Flutter (eyelids)" .)
