Driving sport (4)
I believe the answer is:
golf
'driving sport' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for golf that I've seen before include "The game some say spoils a good walk" , "Irons and woods sport" , "Sport with bunkers" , "To some, it's a good walk spoiled" , "Code word for the letter G" .)
