Jockey Kerrin McEvoy timed his run perfectly to guide Mental to victory in the Group One Patinack Farm Classic at Flemington on Saturday.
McEvoy tracked race favourite Sea Siren all of the way, before producing his mount inside the final 300m and running away with the prize.
Sea Siren battled away well for second, while the Gai Waterhouse-trained Hallowell Belle was third.
But all honours were with the winner, who will now head overseas to continue racing with the powerful Godolphin stable.
"He is a great horse and it's a pleasure to be a part of his career," McEvoy said.
"We were confident he could settle a bit closer in the run today and he let go when I pressed the button, he really exploded."
Trainer Peter Snowden believes Mental has the ability to be more than competitive when racing overseas.
"He goes to quarantine next Thursday and he'll leave our shores on the 17th of December," Snowden said.
"He probably wouldn't have to improve much more to be competitive over there.
"He is probably the best horse we've sent there and he's going there in the best form."
