Clubs linked to golfer's mistakes (8)
I believe the answer is:
clangers
'mistakes' is the definition.
(clanger is a kind of mistake)
'clubs linked to golfer's' is the wordplay.
'clubs' becomes 'c' (abbreviation used in card games such as bridge).
'linked to' is a charade indicator (letters next to each other).
'golfer's' becomes 'langers' (Bernhard Langer).
'c'+'langers'='CLANGERS'
(Other definitions for clangers that I've seen before include "Embarrassing blunders" , "More than one mistake" , "Drop them and make serious mistakes" .)
