Ball game void without pitch (5)
I believe the answer is:
globe
'ball' is the definition.
(synonyms)
'game void without pitch' is the wordplay.
'void' means to remove the middle letters (the word is empty or void of its inside letters).
'without' means one lot of letters goes inside another ('without' can be similar in meaning to 'outside').
'pitch' becomes 'lob' (both can mean to throw).
'game' with its centre taken out is 'ge'.
'ge' placed around 'lob' is 'GLOBE'.
(Other definitions for globe that I've seen before include "Boston, MA's newspaper" , "Earth - sphere" , "Orb, ball" , "Shakespeare's theatre" , "Planet Earth" .)
