By Alamosa out of a half-sister to the group one Melbourne Cup winner Efficient, On The Rocks jumped to the front and set an easy clip before sprinting on the turn.
"It wasn't the plan to lead the race, but after I gave the horse a squeeze out of the barrier he landed there and relaxed," Moloney said.
"I got away with a couple of cheap sectionals and he held a good, strong gallop down the straight."
On The Rocks' performance saw his odds for his autumn target – the group one Vodafone New Zealand Derby (2400m) — tumble from $31 to $12.
"He's a really nice colt, I've got a lot of time for him," Gerard said.
"The inside draw helped dramatically and it was a fantastic ride by Patrick."
The filly Kapoor was on the pace all the way and she chased gamely in the closing 400m to take second ahead of the warm favourite Demonetization.
The previously unbeaten colt settled three back on the fence and was doing his best work in the closing stages.
