Gingernuts was outside Kawi at the top of the straight and the classy Stephen Autridge and Jamie Richards-trained chestnut finished strongly to down the Tarzino Trophy winner Close Up by a short neck.
"I was a bit worried when he started gawking around and he only knuckled down when the other horse came at him," Bosson said. "There's so much improvement left in him."
Kawi finished third after getting into tight quarters between the winner and runner-up close to home with rider Jason Waddell forced to take a hold of the six-time Group One winner, although the incident had no bearing on the result.
Gingernuts, who has group 1 entries for the Caulfield Cup (2400m) and the Melbourne Cup (3200m), is now a firm favourite for the group 1 Livamol Classic (2040m) in a fortnight's time, although his participation isn't guaranteed.
Richards indicated a round table discussion with Autridge and Te Akau principal David Ellis would confirm their path forward."We won't be making any decisions today," he said.
