The powerful Chris Waller stable kicked off Day 2 at The Championships with a winner in the first race on the card at Randwick, the $200,000 Listed ATC Fernhill Mile (1600m) for juveniles.
Brazen Beau colt Diameter had placed only in one of four previous starts, all of them in stakes company, but given a positive ride from Tommy Berry, he produced a stylish effort to win by a length.
A homebred for Godolphin, Diameter is a half-brother to Group I VRC Newmarket Handicap winner Cylinder and Group III winner Parsifal, who were both sprinters, but Chris Waller was confident this colt would relish the mile.
“It’s been good to pick up a few of these lovely horses from Godolphin, and he’s by Brazen Beau (Waller used to train), so we know a bit about them,” said Waller.
“H's always shown us that he'll get a mile, so it gave us the confidence to press towards this race and as a three-year-old, he'll get his chance at some of the good mile races.”
Diameter is the fourth winner from five foals to race from Group III winning Street Cry (IRE) mare Circular, who traces back to the family of champion racehorse and sire Lonhro.
Circular has not had a live foal since Diameter, but was covered last spring by Too Darn Hot (GB).
Diameter is the 31st stakes-winner for I Am Invincible stallion Brazen Beau, who stands at Darley Victoria as does Cylinder, whose first weanlings ill be offered at upcoming sales.
