Put off as spectator, I ran wild (13)
I believe the answer is:
procrastinate
'put off' is the definition.
(thesaurus)
'spectator i ran wild' is the wordplay.
'wild' is an anagram indicator.
'spectator'+'i'+'ran'='spectatoriran'
'spectatoriran' with letters rearranged gives 'PROCRASTINATE'.
'as' is the link.
(Other definitions for procrastinate that I've seen before include "Put off till later" , "Delay, waste time" , "Stall" , "Postpone" , "Defer action" .)
