Kevin Corstens is hoping it will be third time lucky when he saddles Bon's A Pearla in a Group 1 contest, this time in Adelaide.
Bons A Pearla runs in the Australasian Oaks (2000m) at Morphettville on Saturday having competed in the Thousand Guineas (1600m) at Caulfield last spring and earlier in the autumn, finishing third behind Hitotsu in the Australian Guineas (1600m) at Flemington.
Since the Australian Guineas, Bons A Pearla has had a pair of second place finishes, firstly behind Daisies, an opponent on Saturday, in the Group 3 Alexandra Stakes at The Valley before her last start behind My Whisper in the Group 3 Auraria Stakes (1800m) at Morphettville on April 9.
Bons A Pearler returned home following her latest outing and Corstens said the filly only needs to gallop well on Tuesday morning to take her place.
"She's had a few good weeks since she came home from Adelaide," Corstens said.
"Getting her back home, she settles back into a routine. She likes being out in a yard and over there, she didn't have a yard to go out into.
"That's one of the main keys for her, I think."
Corstens said Jack Hill retains the ride on Saturday having ridden the filly over in Adelaide.
He said Bons A Pearler was not bred to run the 2000m journey on Saturday, but being a three-year-old filly, against her own age and sex, she deserved the opportunity.
"He did nothing wrong on her last start and he knows her really well," Corstens said.
"She's a quirky sort of horse, so we've elected to keep him on.
"The 2000 metres is always a throw at the stumps, and she's not bred to get it, but she is a three-year-old against her own sex at set-weights.
"She carried more weight than them last start but back down on equal weights, hopefully it turns out in her favour."
