It was the fifth career victory for the son of Jakkalberry who is prepared by Robert Hickmott at Ballarat.
"It was a super ride and he got the run when he needed it," Hickmott said.
"The natural transition for this horse is to a Rating 78 and there is one next week over a mile and a half, which might come up a bit soon, but we would like to step him up to that distance again soon.
"We can still win those graded races which is terrific.
"He had a bleed as a three-year-old, so we had to give him one year and get his lungs right but now he is a fully set horse, he won't have a problem."
Highland Jakk was bought by Hickmott's brother Michael at the 2018 Karaka yearling sales. He was a $25,000 purchase from Luigi Muollo's Novara Park, home to his late sire Jakkalberry, who was placed in the 2012 Melbourne Cup.
As a three-year-old Highland Jakk placed at Listed level in behind Pancho and subsequent Group One winner Russian Camelot.
