Victoria Derby winner Riff Rocket will spearhead a team of three stablemates in the CS Hayes Stakes - a race that trainer Chris Waller hopes will boost their chances in an early autumn Group 1 contest.

Riff Rocket, Tannhauser and Cap Ferrat run in the Group 3 CS Hayes Stakes (1400m) at Flemington on Saturday as a prelude to the Group 1 Australian Guineas (1600m) at the same venue two weeks later.

Waller said Saturday's race was a perfect starting point for all three as they kick off their autumn campaigns.

"It's not about winning on Saturday but building steadily throughout the prep," Waller said.

The Group 1 Australian Derby (2400m) at Randwick in April is the long-term goal for Riff Rocket as he looks to become a dual Derby winner.

Riff Rocket has raced at Flemington three times, for two wins.

He was a green and immature galloper when unplaced at his second race start but returned last spring to claim the Listed Super Impose Stakes (1800m) on his way to Derby success.

"The Rocket, he loves Flemington," Waller said.

"He does carry a big penalty for being a Group 1 winner, so I guess that brings him back to the field a little bit."

Waller holds a healthy opinion of Tannhauser who is returning to racing after disappointing in two spring runs.

Tannhauser has not raced since beating only two home in the Gloaming Stakes (1800m) at Randwick last October.

"I like this horse a lot," Waller said.

"Things didn't go right for him in the spring when he got an infection, so you can put a line through the whole spring.

"He's a good colt. He will probably be better when he gets to 2000 metres, maybe for a race like the Rosehill Guineas later on."

Maiden galloper Cap Ferrat rounds out the trio.

Cap Ferrat has been placed at Stakes level on multiple occasions and will be having his first start since running in the Spring Champion Stakes (2000m) at Randwick last October.

"He's still a maiden but is Group 1 placed," Waller said.

"He ran second in the Spring Champion Stakes last start, and he's come back well."
