Played to a Yankee fellow! (5)
I believe the answer is:
toyed
'played' is the definition.
('toy' can be a synonym of 'play')
'to a yankee fellow' is the wordplay.
'a yankee' becomes 'Y' (phonetic alphabet: alpha, bravo, charlie etc.).
'fellow' becomes 'ed' (short for Edward).
'to'+'y'+'ed'='TOYED'
(Other definitions for toyed that I've seen before include "was trifling" , "Trifled (with someone's affections)" , "Acted idly" , "Engaged in an activity, but not seriously" , "fiddled" .)
