Golfer's attendant (6)
I believe the answer is:
caddie
'golfer's attendant' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for caddie that I've seen before include "Golf course assistant" , "Assistant to carry the golf clubs" , "assist on course?" , "Golfing assistant" , "A golfer's assistant-adviser" .)
