Kovalica heads the Ladbrokes.com.au market for the feature race at Doomben this Saturday, the Doomben Cup (2000m).
The Chris Waller trained four year old was quite good in defeat last time in the Hollindale and looks suited up in trip again. He holds the call at $3.50.
Detonator Jack has been the firmer at $5.50 and sits on the second line of betting, clear of two time defending champ Huetor, who is at $7.
