Blue Diamond contender Kuroyanagi is doing things Will Clarken has never seen before.
The Group 1-winning trainer is astounded by the physical development of the talented filly and her appetite for work, confident she's going to run a big race in Saturday's $2m feature at Caulfield.
Clarken has been open about the fact he's been searching for an excuse to tip Kuroyanagi out, convinced she's going to be even better as a three-year-old, but she's just thriving.
"It's amazing. Me and (co-trainer) Niki (O'Shea) are just blown away by what she's done," Clarken said.
"I could send people a video of her first gallop this prep and you'd just think it was a different horse. The way she's improved and the way she can handle pressure in a preparation is phenomenal.
"I've never had a juvenile who has strengthened and developed in work. Week-to-week she's getting bigger and stronger and more durable. She's a ferocious doer and nothing fazes her.
"I haven't dealt with a lot of really good young horses like this but she's just obviously got a great constitution."
Kuroyanagi first came to prominence in early January when superstar jockey Jamie Kah made a rare visit home to South Australia to ride her to a dominant victory in a jumpout at Murray Bridge.
She went on to win her debut in soft fashion at Gawler before an agonising second across the border in the Group 2 Blue Diamond Prelude for fillies earlier this month.
"She's just come home and thrived. I haven't had one travel back and handle it so well for a long time," Clarken said.
"That was our main concern as it was the first trip away for a young horse but she's put on weight, she's really above herself and he work has been terrific – we've been able to get two good gallops into her."
With Kah and Blake Shinn, who partnered Kuroyanagi in the Prelude, opting to go elsewhere, Clarken was left searching for a suitable rider and he was watching a recent Sha Tin meeting when it hit him that Brenton Avdulla would be perfect.
"I like to keep an eye on Hong Kong racing because we've got a small pool of horses over there now and he's riding so well," he said.
"I was going through options, I asked a couple of Sydney guys and they had rides up there, so I said to (racing manager) Lachie (Weekley) ‘why don't you ask (Avdulla)'?
"We watched him ride a double at the Chinese New Year meeting and I thought ‘imagine getting him on, it'd be awesome'."
Kuroyanagi is rated an $18 hope with the TAB and Clarken thinks that presents good value.
"The gate (two) to me is not ideal, I would've liked to have drawn out a little bit, but we've got the gun riding her, so that will help," he said
"If she gets a little luck in running, I think she's a genuine each-way chance.
"It's hard to say that going into big Group 1s but she has trained on remarkably well."
