A famous dam was one of few clues about the potential of Our Voodoo Prince before the import's surprise first-up win at Sandown.
Our Voodoo Prince is a son of international star Ouija Board and Chris Waller paid $150,000 for him at a tried sale in England last year.
However, Our Voodoo Prince showed the Chris Waller stable little to match his pedigree in his trackwork before his Australian debut outing.
"He's the laziest horse to gallop, he shows nothing," Waller's Melbourne representative Justine Hales, who rides Our Voodoo Prince in his work, said.
Our Voodoo Prince also struggled in a Rosehill barrier trial on March 4 but produced a spirited finish to swamp his rivals in the Surdex Steel Handicap (1600m).
Jockey James Winks picked up the ride on Our Voodoo Prince after Chris Symons suffered a shoulder injury at trackwork on Friday.
Our Voodoo Prince was the first horse to win from the back of the field at the Sandown meeting which Hales said added merit to the six-year-old's performance.
The son of champion sire Kingmambo could find himself in stakes races during the Brisbane winter carnival if he continued to improve.
Hales said Our Voodoo Prince was the first of the latest influx of Waller-trained imports to travel to Victoria to begin their Australian careers under favourable handicap terms.
"Their ratings are lower down here so it's just easier to start them off here," she said.
The $3.60 favourite Tooleybuc Kid was second ahead of the well-supported ($7) Rugged Cross.
The previously unbeaten Wales raced handy to the speed but was among the first horses beaten before finishing 10th.
