Damien Oliver substituted for race jockey Nash Rawiller aboard Fiorente at trackwork at Flemington yesterday and delivered a glowing report on the likely Turnbull Stakes favourite.
Trainer Gai Waterhouse said Fiorente, and her other horse nominated for the race, Glencadam Gold, were "fabulous chances" and predicted they could run the quinella in the A$500,000 ($565,400) feature at Flemington on Saturday.
"Damien partnered him this morning and he said Fiorente was really fluid in his action and glided over 1400m on the dirt," Waterhouse said.
There are 31 nominations for the Turnbull, which will be whittled down to 16 with Glencadam Gold, among 16 group one winners in the entries, the second emergency as things stand before acceptances.
Darren Weir, the trainer of Melbourne Cup favourite Puissance de Lune, which is 17th in the order, is also counting on an attrition rate. Much will depend on what owner Lloyd Williams decides to do with his team, including 2012 Turnbull winner Green Moon.
