Plague Stone's best performance before Saturday has been his second to subsequent Blue Diamond Stakes winner Written By in the Group Three Prelude in February.
Sent out the $2.10 favourite in the Rosebud Prelude for two-year-olds after two trial wins, Plague Stone made light of his 58kg top weight to power home over the top of Stakes placed filly Witherspoon ($5.50).
Trainer James Cummings said the Listed Rosebud (1100m) in three weeks was the likely next step.
“I liked the way he switched off and they've broken 34 seconds for the last 600 (metres) so that's a good sign,” Cummings said.
“He has carried more weight than the others and I like the look of The Rosebud in three weeks.
“He's beaten a stakes-placed filly in Witherspoon.
“I believe he is a fast sprinter and will get as far as 1200 metres which is why I've started him off now.”
“Over 1000 metres he didn't really get a chance to show a great turn of foot,” he said.
“If he can get 1200 metres that will give him the chance to show that.”
