Anthony Cummings holds no fears that Duporth will confirm Sydney's three-year-old form is superior to Melbourne's in Saturday's Caulfield Guineas.

The Golden Rose winner warms up for the Group One, 1600-metre race with a track gallop on the Caulfield course proper on Tuesday and Cummings said he couldn't be happier with the colt.

"He's looking in very good order and he's done very well since the run the other day," Cummings said.

Duporth is rated an $8 chance on TAB Sportsbet for the Caulfield Guineas with the Mark Kavanagh-trained Bill Stutt Stakes winner Whobegotyou, who is the $3 favourite.

Cummings said the Peter Snowden-trained Aichi's victory in the Group Three Danehill Stakes at Flemington on September 6, where he beat $7 equal second favourite for the Caulfield Guineas Time Thief by a nose, was a sign of things to come from Sydney three-year-olds in Victoria.

"He (Aichi) showed where the form was when he had his first run up the straight, he didn't even know what he was doing and did a few things wrong but he still won," Cummings said.

Duporth suffered a slight muscle tear after his victory in the $1 million Golden Rose in August and returned with a fifth placing to Mentality in the weight-for-age Group One George Main Stakes.

"His run was really good, the last 100 metres was the best part of it. Craig (Williams) gave him a couple of cracks and he responded well," Cummings said.

Regular jockey Hugh Bowman jumps back on Duporth and he agrees with Cummings regarding the colt's Melbourne opposition.

"I don't think the Melbourne three-year-old form is all that strong either," Bowman said.

"His run in the George Main had a lot of merit, he had three or four weeks between runs and had a setback before the run too, so it was a big effort.

"Stepping down from weight-for-age to take on the three-year-olds again is another huge plus for him and he'll be very hard to beat if he recaptures that Golden Rose form."

Larry Cassidy will ride $26 Guineas chance Whitefriars on the Caulfield course proper on Tuesday.

The Rick Worthington-trained colt tried to lead throughout before finishing second to Dreamscape in the Stan Fox Stakes at Randwick on September 27.

"He's done well since the run, it's just a matter of drawing a decent barrier," Cassidy said.

"He had the widest gate in the Stan Fox and we were forced to go forward from there and had to do all the work."
