Attracted some well earned reward (4)
I believe the answer is:
drew
'attracted' is the definition.
(I've seen this before)
'some well earned reward' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'DREW' is hidden within 'well earned reward'.
(Other definitions for drew that I've seen before include "was moving" , "Dragged, sketched" , "Dragged, finished level" , "Entertainer Barrymore" , "took in" .)
