Trainer Jane Chapple-Hyam had flagged a trip to Australia for a shot at the Emirates Stakes with Energia Davos following his last-gasp success in the Stella Artois Handicap at Ascot.
The seven-year-old made a winning start to life under the Newmarket handler following his sale out of Marco Botti's yard.
He wore down his former stablemate Puissant in the final strides of the one-mile (1600m) event under Jamie Spencer.
Although his odds were trimmed from 33-1 to 20-1 for the Cambridgeshire, Chapple-Hyam was quick to point out that the Group One mile handicap at Flemington on November 7 is likely to be the next target.
"He would get in the Cambridgeshire, but you are forgetting that I am from Australia and there is the Emirates Stakes at Flemington, which is the Saturday after the Melbourne Cup," Chapple-Hyam said.
"The quarantine for that starts on October 24, and the Cambridgeshire is on the 26th.
"We have got to make up our mind which race to go for, but we might just say 'yes' to Australia."
