Four-year-old mare Perfect Pitch claimed her first victory since late 2017 on Saturday, winning the Highway Handicap (1500 metres) at Rosehill Gardens.

Jockey Hugh Bowman sat Perfect Pitch sixth off the pace before pouncing on the final stretch to beat the Donna Grisdale-trained Banjo's Voice by 0.1 lengths.

It's her sixth podium finish in seven starts for Dryden's stable, having changed hands from Sydney-based trainer Gary Portelli earlier this year.

"She's been very consistent since I got her and it's the furthest she's ever finished," Dryden said.

"She's earned about $57,000 in prizemoney this preparation with that win, so she's definitely paid her way.

"I think she ran well and might now go to the paddock for a spell."

MORE CANBERRA SPORT

Dryden is hoping to give Perfect Pitch another run before sending her back to the paddock, but will make a decision next week.

If she stays in work, the Canberra trainer will nominate her for another Highway Handicap in a fortnights time.

"I'm still thinking about it. I think she's still a bit immature and has some thickening up to do," Dryden said.

"I think with another break well know how she handles herself.

"That's only her second win so shell go in as a class two and then a class three. She can possibly win another two Highways if everything works out.

"But with her, shes so high in the benchmark ratings weight. Thats whats stopped her from winning since Ive had her, [Saturday] was the lightest weight she's carried for me."

The Kosciuszko-winner Handle The Truth ran fourth in the Ortensia Stakes (1100 metres), finishing 2.8 lengths behind victor Dirty Work.

The final 600 metres was the fastest finish of the day at 32.94 seconds, so Dryden was content with the four-year-old's time.

"He went fantastic [on Saturday]. He came from three or four lengths off [Dirty Boy] so he probably ran 32.5 seconds for his last 600 metres," Dryden said.

"He can't do any better than that, that's as fast as he can go. He ran well but against better runners on the day."

Handle The Truth will likely have another race before having a break, with Dryden eyeing a return to the $1.3 million Kosciuszko later this year.

But first, the veteran trainer will shift his focus to Wednesday's meet at Kensington.

Dryden has nominated three-year-old filly Rockarosa in a benchmark 70 (1400 metres), in what will be her second race for the stable.

Rockrosa joined Dryden's stable from Chris Waller last month and was crowned Queen of the South with a benchmark 66 win on Wagga Wagga Gold Cup Day.

"I really didn't want to send her back to Sydney because thats where shes from and hasn't improved up to her class," Dryden admitted.

"But then again, she's ridiculously rated with only two wins under her. She's a 72 horse in the bush but there's no races for her, so we have to send her to Sydney.

"I think she'll race well but I would be suggesting shes an each way chance."
