Willingly enjoy field sports? (4,1,4)
I believe the answer is:
like a shot
I believe this is a double definition.
'willingly' is the first definition.
(to do something like a shot is to do it willingly)
'enjoy field sports?' is the second definition.
(I've seen this before)
(Other definitions for like a shot that I've seen before include "Lout" , "'Pronto!'" , "enthusiastically?" , "Enjoy a nip" , "to demonstrate without hesitation" .)
