Rhode Island group’s award (6)
I believe the answer is:
riband
'award' is the definition.
(riband means ribbon)
'rhode island group's' is the wordplay.
'rhode island' becomes 'RI' (US postal abbreviation).
'group' becomes 'band' (band can mean a group of people).
'ri'+'band'='RIBAND'
(Other definitions for riband that I've seen before include "decorative strip" , "strip of fabric" , "Four across - is trophy for fastest Atlantic sea crossing" , "Strip of material" .)
