Focus on pitch and contract (6)
I believe the answer is:
target
'focus' is the definition.
(thesaurus)
'pitch and contract' is the wordplay.
'pitch' becomes 'tar' (synonyms).
'and' is a charade indicator (letters next to each other).
'contract' becomes 'get' (synonyms).
'tar'+'get'='TARGET'
'on' is the link.
(Other definitions for target that I've seen before include "Object to be aimed at" , "Object to be attained by archers (or fund raisers?)" , "One aimed at" , "Thing to aim at" , "aunt Sally" .)
