Owner William Bellew is hoping Kieren Fallon can produce Summit Surge with another perfectly timed run in tomorrow's Arlington Million.
The six-times champion jockey delivered Luca Cumani's charge with a telling late burst to win the York Stakes on the Knavesmire last time on what was his first attempt at 10 furlongs for new connections.
The six-year-old was previously trained by Ger Lyons and that win was a first triumph for Cumani after creditable runs in Dubai and Italy.
Cumani won the Million with Tolomeo back in 1983 so Bellew, who has made the trip to America with his family, is keeping his fingers crossed the Newmarket handler can repeat the trick.
"The family often travels with me to see Summit Surge run," said Bellew.
"We are enjoying all this together. They were with me at York to watch him win the York Stakes and they went to Italy with me for his race before that.
"However, the York Stakes was the first time we asked him to go over 10 furlongs.
"We threw him in the deep end for that race, but he responded for us. He's a well-seasoned traveller and he travelled well here.
"Luca is very keen on running in the Arlington Million, so we're going to have a go at it and look forward to another great ride from Kieren Fallon."
Summit Surge will face fellow British raiders Tazeez and Debussy in the race along with last year's victor Gio Ponti.
He will be attempting to become only the second dual winner of the race in the event's history following John Henry's triumphs in 1981 and '84.
Jockeys Shay Barry and Alain Cawley had to be hospitalised following falls at Killarney last night.
Barry underwent X-rays for a suspected fracture of his pelvis at Tralee Hospital, while Cawley dislocated his shoulder. Barry suffered his injury when his mount Hairy Molly took a fatal fall at the final fence in the Handicap Chase while Cawley was hurt when his mount, Inagh Valley, fell four fences from home in the Beginners Chase.
