Jameka has exacted group one revenge on her last-start conqueror, Humidor, in emphatic style, spacing the Australian Cup winner by 6 lengths in the A$1.5 million BMW at Rosehill.
The winner of the Caulfield Cup last spring, the Ciaron Maher-trained Jameka was the equal favourite in the Australian Cup two weeks ago when Humidor collared her to win by a long neck.
The step up from 2000m to 2400m on Saturday was in Jameka's favour, as was the pre-race certainty she would have Lasqueti Spirit to follow.
"It was a super effort today and what a ride by Hughie [Bowman]," Maher said.
"It was one of her target races and I'm just rapt to get it done."
