Wigmore Hall made it three wins for the season and booked a trip to America with victory in the Newmarket Nights Conditions Stakes.
The John Smith's Cup winner was sent off the 7/4 second-favourite behind 10/11 market leader Chabal, who was bidding to rebuild his reputation after his flop in the Dante.
Jamie Spencer was always tracking the Godolphin runner and quickened smartly on meeting the rising ground before going away for a ready length-and-a-half success.
Trainer Michael Bell had talked in terms of a trip to Chicago for the Secretariat Stakes beforehand should all go well -- and the manner of this success will not have put him off.
Borderlescott may run again this season, possibly in the Prix de l'Abbaye, after a bone scan showed the popular sprinter had not suffered a serious injury.
The eight-year-old gelding appeared to damage his near hind quarters when winning the Audi King George Stakes at Goodwood last week.
He was taken to Arundel Veterinary Centre, in Sussex, where he underwent a full examination and it is now thought he had tweaked a muscle.
Although unable to attempt to win the Coolmore Nunthorpe Stakes at York for the third successive year later this month, a trip to France for the Abbaye at Longchamp on October 3 could be back on the agenda.
"He seems OK. There's no fractures there and he's sound at the moment so we'll just go steady away with him," said trainer Robin Bastiman.
"He might even run again this year. We'll just weigh that up as he starts back in training.
"I think he's just tweaked a muscle or something like that somewhere in the back. When they scanned him, the near side of his hip was warmer than the other, but nothing too serious.
"We're just going to go steady away with him and see what happens.
"We'll know a bit more after we've had him a couple of weeks. He'll tell us whether he's right.
"There's a possibility he might be able to run in the Prix de l'Abbaye or something like that, maybe. That race gives us a couple of months, but we'll see."
Connections of Twice Over and Byword admit they will be all out to floor Harbinger at York later this month -- despite the Juddmonte International favourite having a close link to the stud operation of race sponsor Khalid Abdullah.
A stunning winner of the King George VI And Queen Elizabeth Stakes, Harbinger is one of the best progeny so far of Dansili, who never won a Group One in his racing career but has every chance of being crowned top stallion this season.
Byword beat the strong-finishing Twice Over in the Prince of Wales's Stakes at Royal Ascot, before the latter came out to gain compensation for Henry Cecil in the Coral-Eclipse at Sandown.
Abdullah's racing manager, Teddy Grimthorpe, said: "Everyone says it is a win-win situation, but obviously on this particular occasion we'll be trying to beat the good son of Dansili.
"They are in cracking form. Twice Over worked the other morning on the Al Bahathri and seems to have come out of the Eclipse really well. It was always the plan to go here.
"Andre (Fabre) is happy with Byword and he's on course. We've always had a great opinion of him.
"He was disappointing at the end of last year, but this year he has done nothing but improve.
"He gave Goldikova a great race in the Prix d'Ispahan, and at Ascot he travelled so well and really put the race to bed. Twice Over was a little unlucky in running, but I always suspect Byword has a bit more to give.
"It's a race the Prince would dearly like to win and everyone in Juddmonte wants that to happen, but it's exciting because you have the best older horse (Harbinger) coming, Rip Van Winkle, and a top horse from Italy, so it's a great race and has caught the imagination," he added.
