Growing Empire has yet to win at the highest level, but Maher's assistant trainer Jack Turnbull believes it is only a matter of time.
"He has got plenty of weight, but he is a star colt. We've always said it," Turnbull said.
"You look at his form last preparation. Third in the Coolmore, third in The Everest, he got beaten on the line by Southport Tycoon in the Manikato.
"Not many three-year-olds could do that with the travel as well."
Turnbull said the stable had removed the blinkers from Growing Empire in a bid to get him to settle behind the speed on Saturday after racing keenly when seventh in the Group 1 Lightning Stakes (1000m) at Flemington on February 15 when resuming.
"He was exposed to the wind on the inside and he just raced with the choke out a little bit and didn't really travel and relax and get into a rhythm," Turnbull said.
"We'll be riding for cover and then to use his turn of foot.
"If saved up, he is quite electric."
