Hit for one making record (6)
I believe the answer is:
single
I believe this clue is a triple definition!
'hit' is the first definition.
(I know that single is a type of base hit)
'for one' is the second definition.
(synonyms)
'making' acts as a link.
'record' is the third definition.
(I've seen this before)
(Other definitions for single that I've seen before include "Not in a relationship" , "Not married, just the one" , "Solo" , "Ticket To Ride < : > hit" , "Unattached" .)
