Mystic Journey claims Australian Guineas

Mystic Journey on Saturday became the third filly in nine years to win the $1 million Australian Guineas at Flemington, providing trainer Adam Trinder and stable jockey Anthony Darmanin with their first success at Group 1 level.

The Tasmanian filly was heavily backed to preserve her excellent winning record, which she improved to nine wins from 12 starts after the Guineas.

Darmanin rode a composed race aboard Mystic Journey, the filly settling three back on the fence and needing clear galloping room.

Hawkshot rolled along in the lead and appeared the one to beat at the top of the straight as The Inevitable ducked back to the inside rail and Amphitrite left the box-seat to issue her challenge.

But it was Mystic Journey who would claim victory, bursting between The Inevitable and Hawkshot with intent at the 250-metre mark to comfortably win by two-and-three-quarter lengths and emulate the efforts of Shamrocker and Mosheen as the other fillies to have won the race since 2010.

"She relaxed really good in the race, I was travelling well but she was a bit intimidated to go through the gap," Darmanin said.

"But once she burst through it, she's got that great turn of foot and exploded away.

"It's unbelievable, I can't believe it! I never thought I'd get a ride in a Group 1 so to win one … I can't thank Adam (Trinder) enough," Darmanin added as his first Group 1 win came at his ninth attempt.

Meanwhile, it was the first time Trinder, a former leading jumps jockey, had saddled up a runner in a Group 1 race. Mystic Journey was purchased for $11,000 by Trinder from the 2017 Magic Millions Tasmanian yearling sale.

"We bought her as a nice little cheap filly that we thought would do a job for us, never in our wildest dreams did we think we would be in a Group 1," Trinder said.

"But when I legged Anthony (Darmanin) on I said, 'Trust her' and I knew she'd be there for him when he required her to be and she was."

Mystic Journey is virtually assured of being given one of three remaining wildcard entries for the $5 million All-Star Mile at Flemington on March 16 when the selection panel release their picks on Monday.

"We'd be hopeful if she pulls up alright, which we trust she will, I'd like to give her an opportunity at that race," Trinder said.

Mystic Journey is second favourite for The All-Star Mile behind three-time Group 1-winning mare Alizee. 

And if you ask Darmanin, who affectionately dubbed Mystic Journey 'the Winx of Tassie', he's forthright in his assessment of her All-Star Mile chances.

"She'll be winning it," he said.
