A film ends badly for baseball player (9)
I believe the answer is:
fieldsman
'baseball player' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'a film ends badly' is the wordplay.
'badly' indicates an anagram.
'a'+'film'+'ends'='afilmends'
'afilmends' is an anagram of 'FIELDSMAN'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for fieldsman that I've seen before include "who tries to minimize score" , "Maybe cover" .)
