What the dismissed baseball player did that's out of the ordinary?
I believe the answer is:
left field
'out of the ordinary?' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'what the dismissed baseball player did that's' is the wordplay.
I cannot quite see how this works, but
'that's' could be 'ie' and 'ie' is found within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for left field that I've seen is " unconventional".)
