A pitcher for the players (4)
I believe the answer is:
oboe
'a pitcher' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for oboe that I've seen before include "Reed instrument" , "Woodwind instrument of treble pitch" , "Producer of notes" , "Player" , "Double-reed wind instrument" .)
