Wigmore Hall had to settle for second as he tried Grade One company for the first time in the Secretariat Stakes at Arlington.
The Michael Bell-trained three-year-old, winner of the John Smith's Cup and a Newmarket conditions race on his last two outings, was taking a steep rise in company in the 10-furlong heat.
Jockey Jamie Spencer was content to ride a waiting race off a slow pace and he was last into the far turn before following winner Paddy O'Prado into the straight.
Wigmore Hall briefly looked like laying down a real challenge but the Dale Romans-trained winner proved too good, pulling away by a length and a quarter.
Bell said: "We were very happy with him, I think the winner looked a top-class horse. He really wasn't suited by the slow pace, he really needs an end-to-end gallop.
"Something like Hong Kong or Singapore could be possible or maybe Dubai would come under consideration. He's a gelding though and he's only won a handicap and a Newmarket conditions race, so he could go for a Listed race or even a Group Three.
"We will need to sit down and have a chat with the owner. He could be a bit of a globetrotter which is very exciting."
Meanwhile, Debussy swooped late under William Buick to claim the scalp of Gio Ponti and land the Arlington Million. Luca Cumani's Summit Surge, the third British-trained runner, finished fifth under Kieren Fallon.
