Shots with which to start scoring at the Oval, maybe (5)
I believe the answer is:
salvo
'shots' is the definition.
(I've seen this before)
'to start scoring at the oval maybe' is the wordplay.
'to start' suggests taking the first letters.
'at' is a charade indicator (letters next to each other).
'maybe' is an anagram indicator.
The first letter of 'scoring' is 's'.
'oval' with letters rearranged gives 'alvo'.
's'+'alvo'='SALVO'
'with which' acts as a link.
(Other definitions for salvo that I've seen before include "Sudden round of applause" , "Simultaneous burst of gunfire" , "Burst of artillery shots" , "Succession of shots" , "Rapid simultaneous shooting" .)
