Bubblier fans running for top prize (4,6)

Ross

I believe the answer is:

blue ribbon

'top prize' is the definition.
(I've seen this in another clue)

'bubblier fans running' is the wordplay.
'fans' indicates anagramming the letters (I've seen 'fanned' mean this (I've seen this in other clues)).
'running' becomes 'on' (eg when a machine is running it is on).
'bubblier' is an anagram of 'blueribb'.
'blueribb'+'on'='BLUE-RIBBON'

'for' acts as a link.

I've seen this clue in The Guardian.
