Siren Rock has missed a place only twice in 10 starts for Holt since the gelding was transferred from Gold Coast trainer Lee Freedman.
Turning six next month, Siren Rock has won four times for Holt and is coming off a dominant last start win over 1609 metres at Townsville’s Cluden Park on July 4.
“It’s his first start over 2000 metres but on his last run and the way he hit the line I can’t see it being a problem,” Holt said.
“He’s got that will to win which carries him a long way.
“Our aim is to run both in the Townsville Cup but if Siren Rock is a complete failure in the Mackay Cup, then we might freshen him and have a go at the Cleveland Bay.”
Arctic Wolf is enjoying the North Queensland lifestyle since moving north and has won twice in three starts for Holt.
The rising seven-year-old won his first two starts for Holt in Townsville in June before a well-beaten second to the Ricky Vale-trained Namazu in the H.L. Black Memorial over 1800 metres at Mackay last week.
Holt has no concerns about backing up Arctic Wolf seven days after his latest outing.
“Namazu is a very good horse and will be tough competition again but Artic Wolf showed us plenty last start,” she said.
“He’s pulled up superb and hasn’t missed any feed and there’s no doubt he’ll run the trip.”
