The odds on whip getting wet (6)
I believe the answer is:
splash
'wet' is the definition.
(thesaurus)
'the odds on whip' is the wordplay.
'the odds' becomes 'sp' (betting abbreviation for starting price).
'on' is a charade indicator (letters next to each other).
'whip' becomes 'lash' ('lash' can be a synonym of 'whip').
'sp'+'lash'='SPLASH'
'getting' is the link.
(Other definitions for splash that I've seen before include "Spend money freely, like loose water" , "Sound of dive" , "big front page news" , "A Bigger --, Hockney painting" , "Display (a story) prominently in a newspaper" .)
