Abel Handy knuckled down admirably to claim victory in the Newmarket Academy Godolphin Beacon Project Cornwallis Stakes.
Declan Carroll's Yorkshire raider won two of his first three starts before finding the reopposing Sound Of Silence just half a length too strong in a Listed contest at York in late August.
Sound And Silence was the 5-2 favourite to confirm his superiority, with Abel Handy a 9-2 chance in the hands of James Doyle.
Charlie Appleby's Sound And Silence made much of the running and bagged the rail racing inside the final furlong, but Abel Handy eventually wore him down and got up to score by a neck. Mokaatil was a close-up third.
Doyle said: "He had to be very tough. We had a good ding-dong (battle) with Sound And Silence from the two-furlong pole and he toughed it out really well.
"You can't take anything away from this fellow. He's a bonny little horse and Declan seems to have done a fantastic job with him."
Carroll said: "He was very brave. He really wanted that. He's come forward with every run this horse and we were very pleased with him coming into the race.
"Sound And Silence had gone on and won in France and it was always going to be close today. Our horse has stepped up.
"He won't run again this season. We'll put him away and make a plan through the winter for him.
"I think he'll progress."
The Norton-based trainer suffered a huge blow earlier in the season following the death of his star juvenile Santry.
The Harbour Watch colt made a big impression on his second start at York and was only narrowly beaten in the Norfolk Stakes at Royal Ascot.
He was fatally injured during work ahead of an intended appearance in the Gimcrack Stakes at York in August.
"This helps a lot, but Santry had a big future. He was a hell of a horse and we miss him," a clearly emotional Carroll added.
"It's been very tough on everybody. We're still grieving over him, but we'll keep going."
