Golfer Trevino (3)
I believe the answer is:
lee
'golfer trevino' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lee that I've seen before include "The sheltered side - of Cork's river?" , "Protection" , "Commander of the Confederate States Army in the American Civil War" , "Sheltered from the wind in Cork, perhaps" , "Cork river" .)
