Try out striker for international (4,5)
I believe the answer is:
test match
'international' is the definition.
(cricket international)
'try out striker' is the wordplay.
'try out' becomes 'test' (synonyms).
'striker' becomes 'match' (a match can be struck).
'test'+'match'='TEST MATCH'
'for' acts as a link.
(Other definitions for test match that I've seen before include "Sort of game" , "sporting event" , "may involve man dealing with maiden" , "14 [NATIONAL] team meeting" , "Ashes tie, perhaps" .)
