American's crisp approach to green (4)
I believe the answer is:
chip
I believe this is a double definition.
'american's crisp' is the first definition.
(a crisp to a British person is called a chip in US)
'approach to green' is the second definition.
(golf shot)
(Other definitions for chip that I've seen before include "nick" , "Flaw" , "Small fragment, off the old block possibly" , "Small fragment (of potato?)" , "Gambling counter; piece of potato" .)
