Wells Farhh Go, who leapt to the forefront of the William Hill St Leger betting with victory at Newmarket last week, is set for just one run before the Classic on September 15.
And although Tim Easterby admitted on Monday to being impressed with new favourite Kew Gardens in Saturday's Grand Prix de Paris, he warned that his colt gives him as good a chance as he's ever had at Doncaster.
The North Yorkshire trainer won the Leger in 2002 with Bollin Eric, who warmed up in York's Great Voltigeur Stakes – which is where Wells Farhh Go is set to head after his game success in the Bahrain Trophy at Newmarket.

"I think we'll go straight to York," said Easterby. "The plan was to go to Goodwood but we might skip Goodwood as we want to go for the Leger and we want to save a bit if petrol for that. I think he's got as good a chance as anything I've ever had, definitely."
Wells Farhh Go is a best-priced 12-1 chance for Doncaster following his all-the-way two length Group 3 win over a mile and five furlongs last Thursday.
"He really knuckled down to it at Newmarket," said Easterby. "We always thought he would do that and he proved it. He did a really good job – he proved he's a proper stayer.
"The Leger will suit him ideally, but I was impressed with Kew Gardens in France and he looks the one to beat."
Wells Farhh Go, last year's Acomb Stakes winner, had finished only sixth in two previous outings this term but his trainer said: "I wasn't worried. He wasn't right and it took a long time to get him ready.
"He had a few little issues, we had a problem with his teeth, then he had a little bit of gravel. And at Ascot we made a cock-up with the riding instructions, I told David [Allan] to drop him in and it was the wrong thing to do,. They went no pace, they crawled, then sprinted, and it was hopeless."
Easterby, speaking at the launch of the Go Racing In Yorkshire Summer Festival, which gets under way at Ripon on Saturday, is eyeing the Molecomb Stakes at Goodwood with smart two-year-old Vintage Brut.
He is confident that the colt, who was bought by Leicester City owner Vichai Srivaddhanaprabha for £280,000 at the Goffs London sale on the eve of Royal Ascot, is better than he showed when a beaten favourite for the Norfolk Stakes – and reckons the sale procedure may have contributed to his downfall.
"He was a bit free at Ascot and didn't fire – we didn't see the true horse," he said.
"They do a pre-sale vetting, which takes them all morning and they have to give them sedative to scan them and to x-ray them. He was sedated for something like three hours and I think that affected him – everybody says it doesn't but I'm sure it did, it was only a week or ten days before the race."
