Trekking took out Sunday's Listed Testa Rossa Stakes (1200m) after racing in Sydney at the start of his preparation.
After notching two wins and a second from three starts, trainer James Cummings elected to switch the four-year-old to Melbourne.
Ridden by Kerrin McEvoy, Trekking was heavily-backed from $3.30 to run the $3 favourite and held off a determined challenge by Japanese import Kemono ($5) to win by 1-1/4 lengths.
Heart Of A Lion ($81) flashed home for third, a half-length away.
“That was impressive. It's good to see my horses draw a nice barrier and get a nice run,” Cummings said.
“He's obviously made huge leaps and bounds this campaign but I'll be careful about being too ambitious while he's able to keep going through his grades.
“He was on the limit today but we'll keep going, try and place him well and see if he can win again, especially ridden like that.”
