Guy in cricket side leaving Somerset's ground (5)
I believe the answer is:
taunt
'guy' is the definition.
(thesaurus)
'cricket side leaving somerset's ground' is the wordplay.
'cricket side' becomes 'on'.
'leaving' is a deletion indicator.
'somerset's ground' becomes 'taunton'.
'taunton' with 'on' taken out is 'TAUNT'.
'in' is the link.
(Other definitions for taunt that I've seen before include "Sarcastic challenge" , "Tease hurtfully" , "Guy" , "Goad, provoke" , "Thing said to anger or wound" .)
