Barrage from Surrey's opener excited Oval (5)
I believe the answer is:
salvo
'barrage' is the definition.
(thesaurus)
'surrey's opener excited oval' is the wordplay.
'opener' suggests taking the first letters.
'excited' is an anagram indicator.
The first letter of 'surrey' is 's'.
'oval' is an anagram of 'alvo'.
's'+'alvo'='SALVO'
'from' acts as a link.
(Other definitions for salvo that I've seen before include "Rapid simultaneous shooting" , "Simultaneous firing of weapons" , "Ovals (anag)" , "Firing of guns as a salute" , "Fusillade, volley" .)
