Masters golf here as impressive adult (7)
I believe the answer is:
augusta
'masters golf here' is the definition.
(Augusta, Georgia, venue for the Masters Tournament)
'impressive adult' is the wordplay.
'impressive' becomes 'august' (I've seen this before).
'adult' becomes 'a'.
'august'+'a'='AUGUSTA'
'as' is the link.
(Other definitions for augusta that I've seen before include "23 [LOVELACE] 's first name" , "Graham Greene's travelling aunt" , "US state capital - girl's name" , "Lady Bracknell" , "Algernon's aunt (Importance of Being Earnest)" .)
