Illustration of batting position (8)
I believe the answer is:
instance
'illustration' is the definition.
(I've seen this before)
'batting position' is the wordplay.
'batting' becomes 'in'.
'position' becomes 'stance' (stance is a kind of position**).
'in'+'stance'='INSTANCE'
'of' is the link.
(Other definitions for instance that I've seen before include "Specimen" , "Exemplify" , "An insect (anag.)" , "Occasion" , "Case in point" .)
