"That's why he's paid the big retainer," said Jamie Richards, who trains in partnership with Stephen Autridge.
"He's a lovely, big horse and he pinned his ears back, he was in for the fight."
The stable's number one jockey was having his first race day ride on Age Of Fire, but Bosson had been in a confident pre-race mood.
"He is a lovely colt and his work in the last few weeks had been outstanding," he said. "He's a big horse, but light on his feet.
"I was a little bit worried across the top when there wasn't much speed, but once I got into the clear he showed that powerful finish.
"Well done to Stephen and Jamie and the team — another group one for the tangerine."
Age Of Fire shares favouritism for the group one Vodafone New Zealand Derby (2400m) at $7 with Demonetization and he is now likely to take on the older horses ahead of the Ellerslie classic.
"My gut feeling is that we'll go to the Herbie Dyke Stakes to give him another chance at a Group One," Richards said, referring to the weight-for-age feature at Te Rapa on February 10.
Hallmark Stud will offer a sister (Lot 172) to Age Of Fire at the Book 1 Sale at Karaka on January 28.
