Pop runs in front of lady (5)
I believe the answer is:
burst
'pop' is the definition.
(thesaurus)
'runs in front of lady' is the wordplay.
'runs' becomes 'r' (cricket abbreviation).
'in' indicates putting letters inside.
'front of lady' becomes 'bust'.
'r' placed within 'bust' is 'BURST'.
(Other definitions for burst that I've seen before include "Rupture" , "Explode, break open" , "Collapse" , "Pop" , "Explode, erupt" .)
