Tommy Berry is the jockey-of-the-moment but it is his past efforts that have rewarded him with the Group One ride on Silent Achiever in Saturday's Queen Elizabeth Stakes.

Berry has enjoyed a spectacular autumn carnival in which he has won Sydney's two biggest races - the Golden Slipper on Overreach and Doncaster Mile aboard Sacred Falls.

No doubt that vein of form has held him in good stead but it has been his work behind the scenes that led to trainer Roger James approaching Berry to partner Silent Achiever.

The Kiwi mare has been ridden by James McDonald in all four starts this campaign.

McDonald isn't riding at Randwick on Saturday due to suspension and even if he was, he would have been aboard star three-year-old It's A Dundeel in the Queen Elizabeth (2000m).

In his absence, James approached Berry for the mount.

"I've helped Roger James out when he's been in Sydney with horses and ridden some trackwork for him," Berry said.

"When James McDonald was suspended two weeks ago he asked me if I could take the ride.

"I've ridden her three times in the last week-and-a-half and she is really working well.

"She's never been the flashiest trackworker but I'm satisfied she is spot-on for Saturday."

Silent Achiever failed by a head to overhaul three-year-old Fiveandahalfstar in The BMW and it's another member of that age group who looms as the one to beat on Saturday.

It's A Dundeel has been breathtaking this autumn, making a clean sweep of the three-year-old triple crown with a six-length romp in the Australian Derby two weeks ago.

He is the $1.35 favourite ahead of Silent Achiever ($8), who shares the second line of betting with high-class import Reliable Man.

Berry respects the favourite but he doesn't believe It's A Dundeel is unbeatable.

"It's a hard race for three-year-olds to win as past records show," he said.

"It's A Dundeel is a pretty good horse. I'm looking forward to the clash."

Intergaze in 1997 was the last three-year-old to win the Queen Elizabeth.
