Trueshan lit up Doncaster as he returned to his best to register a remarkable success in the Betfred Doncaster Cup Stakes.
Retirement appeared to be looming when the seven-year-old disappointed earlier in the season, but given a wind operation and a 135-day summer break, Alan King's charge roared back to form on Town Moor.
Victory looked unlikely in the early stages of the Group Two contest as Trueshan refused to settle for Hollie Doyle, travelling keenly when held-up behind the steady early pace set by Ryan Moore aboard Broome.
Doyle allowed her mount to stride on approaching the turn for home and it proved to be a race-winning move from the rider as the staying veteran powered his way to the head of affairs.
With the rest of the field remaining glued to the inside rail, Trueshan set sail solo up the centre of the track, before edging his way across to battle John and Thady Gosden’s Sweet William who had emerged from the pack to lay down a stern challenge.
Trueshan, however, would not be denied and he stormed to the line to win by a length and a quarter.
Doyle said: "That was definitely not Plan A! It’s not the first time he’s given me a rodeo either, but he can still win because he’s so superior. He’s back to his best. To do it that way round he must be.
"He actually can settle beautifully if he can use himself but I just needed him on a stride. The thing today was we were going a pedestrian pace and it was breaking his stride, so when you are on a big horse like that I just let him bowl along and it was going to be make or break.
"He’s the kind of horse that when you let him have that bit of rein and use himself, he then doesn’t go anywhere!
"I had walked the track and spoken to the clerk of the course who told me that the better ground was up the middle. Obviously that was a risk because we raced on it yesterday but it worked out OK.
"The wind op has definitely helped. At Ascot earlier this year, we hacked around and he curled up a furlong and a half out whereas today he proved he’s back to his best."

Big Evs (9-4F) also bounced back to his very best with a devastating display in the Carlsberg Danish Pilsner Flying Childers Stakes.
Mick Appleby's speedster has struck gold at both Royal Ascot and the Goodwood Festival, but having been tasked with taking on his elders in the Nunthorpe last time, was unable to get involved and was ultimately one of the disappointments in York’s premier sprint.
Back to racing against his own age group, the son of Blue Point put his rivals to the sword from the very start to add this Group Two prize to his growing CV and having been fast away from the stalls in the hands of Tom Marquand, he scorched his way up Town Moor as his rivals chased the pacey youngster’s tail in vain.
The two-and-three-quarter-length winner now appears to have booked his ticket to the Breeders’ Cup in November.
Appleby said: "After he jumped out of the stalls there wasn’t really a doubt. Once he got three or four lengths on them they weren’t going to catch him. You’ve got to be up the front on this ground.
"It’s not the ideal ground for him but he’s got the job done well. He’s won a Molecomb and the Flying Childers on soft ground now.
"We just had to put a line through the Nunthorpe. I think he just had an exceptionally hard race at Goodwood, I think that just took its toll.
"I think it will be the Breeders’ Cup next for the Juvenile Turf Sprint, straight there. It’s five furlongs at Santa Anita which should be ideal. If he can get the rail he could be difficult to peg back."
