"He's a top class horse, one of the nicest two-year-olds I've sat on for quite a while," he said.
"He's a Karaka Million horse and maybe even the Golden Slipper."
Barn mate Avantage, a daughter of Fastnet Rock, has won both her starts at Riccarton by wide margins.
"She'll have one more run before the Karaka Million, but we've yet to decide when that will be," Richards said.
Avantage was to have taken on Al Hasa in the Welcome Stakes before a minor issue delayed the clash.
"She had a bit of shin soreness so we elected to back off and she's jumping out of her skin now," Richards said.
"They are both on target for the Karaka Million." NZ Racing Desk
