Boom youngster Hydro Star has opened favourite with Sportsbet.com.au for one of the features at Caulfield on Saturday, the Vain Stakes (1100m).
The John McArdle trained three year old could not have been more impressive when winning on debut at Sandown, so much so that the stable sends him straight to Stakes company. He is favourite at $2.80.
He holds the call over Rulership, who opened equal favourite at $2.80 but has drifted to $3. The early firmer has been the Team Corstens runner Ranting, who opened $6.50 and has come in a full point.
Larimer Street is an $8 chance.
