Excellent spinner having fine match (3-6)
I believe the answer is:
top-flight
'excellent' is the definition.
(I've seen this before)
'spinner having fine match' is the subsidiary indication.
'spinner' becomes 'top' (something that spins).
'having' is a charade indicator (letters next to each other).
'fine' becomes 'f' (abbreviation).
'match' becomes 'light' (I've seen this in other clues**).
'top'+'f'+'light'='topflight'
(Other definitions for top-flight that I've seen before include "Excellent -- best possible" , "Of the highest class" , "Highest level" , "Superior" .)
