Slip, perhaps, if turning round tree (7)
I believe the answer is:
fielder
'slip' is the definition.
(cricket term)
'if turning round tree' is the wordplay.
'turning round' says the letters should be written backwards.
'tree' becomes 'elder' (elder is a kind of tree).
'if' back-to-front is 'fi'.
'fi'+'elder'='FIELDER'
'perhaps' is the link.
(Other definitions for fielder that I've seen before include "one in gully, perhaps" , "cover, perhaps" , "Player" , "Slip or cover, maybe" , "Slip, perhaps" .)
