South Australian trainer Dan Clarken has all but declared his runner in Saturday's Listed Port Adelaide Guineas (1600m) at Morphettville.

Harleymoven created a huge impression over 1550m at Morphettville Parks last month, circling the field and charging away to a 4.5-length demolition job.

Although Harleymoven (+270 at Bovada) is stepping up in grade tomorrow, co-trainer Dan Clarken – who prepares the emerging stayer with Oopy Macgillivray – has advised punters to expect more of the same in the 3YO feature.

“If he gets the right run, he'll do the same thing,” Clarken predicted.

“When he gets out and gets clear air, he really lengthens, and we saw that last start – he just went whooshka. To get to these good races, you've got to see them do that, so that run has just cemented where he's at.

“Hopefully we get the same scenario Saturday: bottled up early, getting to the outside and lengthening.

“I'm totally convinced the horse is in great order. He's got an electric turn of foot when he gets out and gets going.”

At his only previous 1800m start, Harleymoven struggled home into fifth behind Morty in an average benchmark 68 event at Morphettville, but Clarken has advised punters to disregard that run as any guide.

“He drew wide, he stayed wide, he saw too much daylight the entire journey, and he pulled his head off,” Clarken said.

“He was outside the leader turning for home, and he probably did a great job to box on and finish where he did that day.

“Drawn two this weekend he should get buried away somewhere early, and with a bum in his face he should just relax.

“Hopefully the horse has learned to be a racehorse now.”

Meanwhile, Clarken is bemused about the price of his other young stayer, The Map, in the Auraria Stakes (1800m) earlier in the day.

The Map charged home for third behind Mac ‘N' Cheese in the 1600m Clare Lindop Stakes, and Clarken believes the two should be closer in the market.

“The Map went enormous in the Clare Lindop, she's drawn well and I reckon the extra 200m on Saturday will suit her,” he said.

“The discrepancy in price between Mac ‘N' Cheese and her is unbelievable. She's about 30/1 and there was a bit more too – 40/1 at one stage.

“She hit the line hard, she had no favours in the run, she was last turning for home, and she was best through the line.

“Put it this way, I'm looking forward to it.”

Clarken said Harleymoven is being aimed at next month's Group 1 South Australian Derby (2500m), while The Map is on track for the Australasian Oaks.

“If we can get him into the Derby and her into the Oaks, it'll be pretty exciting,” he said.

Melbourne filly Daisies, a strong Group 3 winner over a mile at Moonee Valley last start, is favourite for the Guineas at around +120.

She is one of five fillies that accepted for the Guineas, including the talented Danny O'Brien-trained Blackcomb (+1000).
