Sporting rarity, huge winger? (9)
I believe the answer is:
albatross
'winger?' is the definition.
(albatross is a kind of bird)
'sporting rarity huge' is the wordplay.
I cannot quite see how this works, but
'huge' could be 'os' (abbreviation for outsize) and 'os' is present in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for albatross that I've seen before include "The Ancient Mariner's burden" , "shot by elderly sailor" , "Large seabird or constant burden" , "Very good score" , "not achieved by many golfers" .)
