Trainer Gary Portelli says only bad luck can beat Fireburn in the Champagne Stakes.

Warwick Farm trainer Bjorn Baker has made a surprise decision to go bush with his boom trial winner Miss Amelia for her race debut at Nowra on Sunday.

The Gai Waterhouse-trained Pierro vindicated his trainer's faith in him by going through the Autumn undefeated claiming Saturday's Group 1 Champagne Stakes over 1600m at Randwick in devastating fashion.

Champion colt Pierro has joined an elite group of six to have won Sydney's two-year-old Triple Crown by producing another dominant win in the Moet & Chandon Champagne Stakes at Randwick today.
