Stick, holding mind adjusted for sport (9)
I believe the answer is:
badminton
'for sport' is the definition.
(badminton is a kind of sport)
'stick holding mind adjusted' is the wordplay.
'stick' becomes 'baton' (term for a stick or staff).
'holding' indicates putting letters inside.
'adjusted' indicates anagramming the letters.
'mind' is an anagram of 'dmin'.
'baton' going around 'dmin' is 'BADMINTON'.
(Other definitions for badminton that I've seen before include "22 Across sport" , "Seat of the Duke of Beaufort - racket game" , "Game with shuttlecocks" , "Game played with a shuttlecock" , "Game using shuttlecock" .)
