Marco Botti's Jakkalberry won the inaugural running of the American St. Leger Stakes at Arlington Park on Saturday.
The six-year-old was sent off the 8/5 favourite by Chicago punters and he obliged at those odds after getting the better of long-time leader Ioya Bigtime in the straight.
Colm O'Donoghue settled his mount in fifth in the early stages but was always going well as Ioya Bigtime set the fractions up front.
O'Donoghue mounted his challenge rounding the final turn and although he didn't pass the game frontrunner with ease the British raider was well on top at the line.
The pair pulled clear with Ioya Bigtime second, while John Gosden's Zuider Zee was third under William Buick.
"He travelled well and I liked the way he picked up. Obviously he stays very well," said Botti.
"The plan is the Melbourne Cup. He will go into quarantine in September, so he won't run again in Europe.
"There are races like the Caulfield Cup as well as the Melbourne Cup to aim at if all goes well."
Jakkalberry was ridden for the first time by Irish jockey Colm O'Donoghue, who said: "It was a solid run race. He got into a good position and travelled really well. Mr Botti said he needs really firm ground.
"He ran a solid race."
