Randwick Guineas winner Shadow Hero has been the early firmer with Sportsbet.com.au when it comes to the Rosehill Guineas (2000m) this Saturday.
The Mark Newnham trained three year old was given a 12/10 steer from Josh Parr to win at Randwick last time out and will love the rise to 2000m. He opened $3.70 and has firmed to $3.60, clearly sitting at the top of betting.
Castelvecchio, who gets Craig Williams back on, is a $5.50 chance. Warning, who was an eye catcher at Randwick has eased to $7 from $6 while at longer odds, there has been specking for Chains Of Honour ($61-$41).
