Sweet support for golfer holds off (6)
I believe the answer is:
toffee
'sweet' is the definition.
(toffee is a kind of sweet)
'golfer holds off' is the wordplay.
'golfer' becomes 'tee' (I can't justify this - if you can you should give a lot more credence to this answer).
'holds' means one lot of letters goes inside another.
'tee' going around 'off' is 'TOFFEE'.
'support for' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for toffee that I've seen before include "Caramel" , "Brittle confectionery" , "Sugar/butter sweet" , "Chewy confectionery" , "Confectionery made from sugar and butter" .)
