Worked miracle to recover (7)
I believe the answer is:
reclaim
'recover' is the definition.
('reclaim' can be a synonym of 'recover')
'worked miracle' is the wordplay.
'worked' is an anagram indicator.
'miracle' is an anagram of 'RECLAIM'.
'to' is the link.
(Other definitions for reclaim that I've seen before include "Make (land) available for use" , "Get back (airline baggage)" , "From sea, rescue" , "civilize" , "Retrieve, recover" .)
