Cricket perhaps divided by Pakistan's opening review (7)
I believe the answer is:
inspect
'review' is the definition.
(thesaurus)
'cricket perhaps divided by pakistan's opening' is the wordplay.
'cricket perhaps' becomes 'insect' (cricket is a kind of insect).
'divided by' is an insertion indicator.
'opening' indicates taking the first letters.
The first letter of 'pakistans' is 'p'.
'insect' enclosing 'p' is 'INSPECT'.
(Other definitions for inspect that I've seen before include "Look over carefully" , "vet" , "Scrutinize, audit" , "Examine closely" , "Study" .)
