Zoustyle ($1.40) made it two wins from as many starts when he beat Red Doulton ($11) by 3 1/4 lengths in the QTIS Two Year Old (1000m).
His time of 58.81 seconds was just outside the class record of 58.75 which was a good effort on a soft track.
The gelding ran a class record for 100m at Doomben at his first start again on a soft track.
Zoustyle has been hailed a future champion by racing critics but Gollan has steadfastly refused to join them.
“He is a nice horse and that was a good effort again but I would like to see what he can do against better class horses before I start getting carried away,” Golan said.
“We have a lot of options, the Sydney or Melbourne spring or the Brisbane summer but I want to see how he pulls up before I make any form plans.”
“It is a bit scary how good he could be,” Stewart said.
