Batting posture, for example (8)
I believe the answer is:
instance
'example' is the definition.
('instance' can be a synonym of 'example')
'batting posture' is the wordplay.
'batting' becomes 'in'.
'posture' becomes 'stance' (stance is a kind of posture).
'in'+'stance'='INSTANCE'
'for' is the link.
(Other definitions for instance that I've seen before include "Case or example from ancients" , "Exemplify" , "'Example, illustration (8)'" , "Canniest (anag) - occurrence" , "Particular example" .)
