International, where young woman crosses pitch (6)
I believe the answer is:
global
'international' is the definition.
(I know that international can be written as global)
'young woman crosses pitch' is the wordplay.
'young woman' becomes 'gal' (synonyms).
'crosses' is an insertion indicator.
'pitch' becomes 'lob' (both can mean to throw).
'gal' placed around 'lob' is 'GLOBAL'.
'where' acts as a link.
(Other definitions for global that I've seen before include "Comprehensive" , "All-encompassing" , "Sphere-shaped" , "blanket" , "Like big village" .)
