Kennewell said the filly would head to Merricks Station on the Mornington Peninsula on Wednesday to “let her hair down” for three or four days before being prepared for the fillies division of the Blue Diamond Preview (1000m) at Caulfield on January 26.
Ridden by Joe Bowditch, Jedastar was backed from $17 to $13 before scoring a 2-1/4 length win over Enood ($9.50) with For Love ($10) 1-1/4 lengths away third.
“I don't think she's mentally ready for the Gold Coast,” Kennewell said.
“I think she'll be better off around a bend, on her home track and over 1000 metres so hopefully she'll be a jump and run job.”
Kennewell went to $250,000 to secure Jedastar at the Gold Coast sale last January and was determined not to leave without her.
He has a number of horses by I Am Invincible in his stable and says the filly is a precocious type that fits his criteria.
Bowditch described Jedastar as a “hot-headed little thing” and her manners on Tuesday determined how she performed.
“They've got to have a good attitude to make it as a racehorse and hers was spot-on today,” Bowditch said.
“First time at Flemington, racing down the middle of the track, they can get a bit lost, so once she found the fence she was always going to be hard to beat.”
