West Indies, say, upset cricket side getting duck (6)
I believe the answer is:
wigeon
'duck' is the definition.
(wigeon is a kind of duck)
'west indies say upset cricket side' is the wordplay.
'west indies' becomes 'wi'.
'say' becomes 'eg'.
'upset' is a reversal indicator.
'cricket side' becomes 'on'.
'eg' written backwards gives 'ge'.
'wi'+'ge'+'on'='WIGEON'
'getting' acts as a link.
(Other definitions for wigeon that I've seen before include "Breed of duck" , "Type of duck" , "flier" , "Duck, related to mallard and teal" , "Freshwater duck" .)
