Volley from Slav drifting over (5)
I believe the answer is:
salvo
'volley' is the definition.
(I've seen this before)
'slav drifting over' is the wordplay.
'drifting' indicates anagramming the letters.
'over' becomes 'o' (cricket abbreviation).
'slav' with letters rearranged gives 'salv'.
'salv'+'o'='SALVO'
'from' is the link.
(Other definitions for salvo that I've seen before include "Succession of shots" , "reservation" , "Unusual excuse" , "Rapid simultaneous shooting" , "Simultaneous burst of fire" .)
