Glamour mare Atlantic Jewel has extended her unbeaten run to nine with an effortless victory in the Stocks Stakes at Moonee Valley in Melbourne.

The pin-up girl of Australian racing was sent out at Black Caviar-type odds against only five rivals and she scored with ease from Oasis Bloom and Oriental Ruby.

The Group Two race at weight-for-age for fillies and mares was a mere training gallop for Atlantic Jewel, earning her connections $132,000 for the day out.

Trainer Mark Kavanagh opted for the Stocks as the path of least resistance for Atlantic Jewel after her dazzling win from a 70-week break in the Memsie a fortnight ago.

He took issue with suggestions that he chose the race to dodge open company in the Dato Tan Chin Stakes later in the day, which also featured stable-mate Super Cool.

"If you want to look after the longevity of the horse, a mile (gallop), sprinting home three (furlongs) is the way to do it," he said.

"We want her to keep coming to the races as much as possible and we want to keep her in good order, so they were both Group Two, both weight-for-age, this one's for mares and it's just a no-brainer.

"I just couldn't understand why anyone would even criticise or question me. I thought it was ridiculous."

Michael Rodd could possibly complain of whiplash later after taking several looks around as her guided Atlantic Jewel ($1.06) to the lead turning for home.

He only slapped her on the shoulder to keep her mind on the job in the closing stages to win by 2-1/2 lengths.

"Where she beats them is at the 600, where they're under pressure she hasn't changed gears yet and she puts them away very quickly," Rodd said.

"But it's not going to get any easier from here on in."

Rodd said he's excited by the hype that continues to grow around Australia's latest undefeated superstar.

"We've had more than a preview with what Black Caviar and what she did for racing, and obviously this isn't anywhere in the realm of what she brought to the track, but it's nice to think that she's brought a few more people through the gates ... the momentum will keep building."

Kavanagh said there was plenty of improvement still to come in the horse and she could back up in the Group One Underwood Stakes (1,800m) next week.

"She's had a nice gallop on the course proper today so nothing's out of the question at this stage," he said.

"The Cox Plate is her aim ... she'll be ready that day."

Atlantic Jewel remains a clear-cut $2.70 favourite for the Cox Plate, which will be run on October 26.
