She's Clean's victory in Saturday's Triscay Stakes at Warwick Farm has chalked up significant milestones for her trainer and also her sire.

Her win over Appearance in the Listed sprint gave premier trainer Chris Waller his 100th Sydney winner for the season to put the record of 156 in his sights with five months remaining.

It brought up a century of stakes winners for She's Clean's sire, Arrowfield's Redoute's Choice who is standing the northern hemisphere season at the Aga Khan's stud in France.

Her win wasn't without incident with Sam Clipperton's mount California Storm shifting out and causing a chain reaction which led to Appearance ($4.40) copping a bump and being forced onto the winner.

After they steadied up, She's Clean ($4) prevailed by a short half head.

The win capped a big week for Waller after he and wife Stephanie welcomed a daughter, Nikita Jayne, on Wednesday.

It also holds extra significance for Waller as she is raced by the Ingham family.

When patriarch Bob Ingham sold his Woodlands concern to Sheikh Mohammed he anointed Waller as the trainer of his new venture and spent more than $20 million on yearlings in 2008.

"It is a great feeling to reach the mark," Waller said.

"We won this race last year with Dystopia for the Inghams who have been instrumental in my career.

"We are constantly refining things in the stable and I know we can still improve so there is always something to achieve."

Not long after She's Clean won the Triscay (1200m), Foreteller took out the Group Two Sir Peter Young Stakes (1800m) at Caulfield.

Waller has recently acquired 10 boxes at Flemington and will send more horses south in the coming months.

Rival trainer Guy Walter and jockey Blake Shinn were disappointed by Appearance's defeat but were all smiles 40 minutes later when Jacquinot Bay won the Canley Heights Hotel (1300m).

It was Jacquinot Bay's sixth win from seven starts and Walter believes he can take big steps.

"He's entered for the Doncaster and I think he might be up to that standard. In fact I'm confident he is," Walter said.

"He has a long way to go but he wants to win."

Shinn agreed, saying Jacquinot Bay was a tired horse at the 100m after the hard slog on the heavy track but his will to win got him to the line.

"He had had enough," he said.

"But he is all guts and determination."
