Better fiddle gas meter! (8)

I believe the answer is:

gamester

'better' is the definition.
(thesaurus)

'fiddle gas meter' is the wordplay.
'fiddle' indicates an anagram.
'gas'+'meter'='gasmeter'
'gasmeter' with letters rearranged gives 'GAMESTER'.

(Other definitions for gamester that I've seen before include "Better" , "Betting man" .)

I've seen this clue in The Telegraph.
