Andronikos returned to his best with the aid of a tongue strap to win the At The Races Red Button Betting Doncaster Stakes at the Town Moor course.
The Paul Cole-trained colt had looked a useful juvenile judged on his second place in the Group Two Gimcrack Stakes, but he then flopped in the Mill Reef Stakes at Newbury last month.
Encouraged by the horse's work when fitted with a strap, it was decided to use it in a race and it paid off handsomely in this Listed event over six furlongs.
Hitting the front a furlong out, the 100-30 shot galloped on strongly to beat Harvest Warrior by two lengths and complete a quick double for Kieren Fallon, successful on Motivator in the feature Racing Post Trophy.
''He's been working well at home with a tongue strap and it's made the difference. It will have done his confidence a power of good,'' said the trainer's son, Oliver.
''He's going to be a good horse for next year.''
Godolphin's bandwagon rolled on when Meshaheer took the Racing Post Weekender Conditions Stakes in good style.
The Dubai operation landed a three-timer at Doncaster on Friday and Descartes scored for them at Newbury.
Meshaheer (100-30) kept up the good work with a comfortable two-length call over Millennium Force, with Quito a neck away in third.
Willie Supple settled the colt in mid-division before producing him to lead well inside the last of the seven furlongs and record a convincing success.
Meshaheer, who was having only his third start of the year, is unlikely to race again this term.
Tempsford (10-1) bounced back from a disappointing run in the Cesarewitch the previous Saturday by making all the running in the Racing Post £1 Million totetentofollow Handicap.
Seb Sanders made the mile-and-a-half race a true test of stamina and had most of his rivals in trouble in the straight.
Millville came out of the pack but was still a length and a quarter down on the Sir Mark Prescott-trained winner at the line, with Bendarshaan a further length away in third.
''He didn't settle in the Cesarewitch. Today when I took him to the front he pricked his ears and stayed on really well,'' said Sanders after riding his 160th winner of the season.
Connections of the second and the third revealed that their horses were likely to return to Town Moor for the November Handicap on the last day of the turf campaign in a fortnight.
Local trainer John Balding took the honours when saddling the first and third in the Rectangle Group Handicap with half-brothers Matty Tun and Tom Tun, both owned by Olga Tunstall.
Matty Tun (16-1) won the six-furlong contest by three-quarters of a length from Whitbarrow.
Mark Johnston continued his fine end to the season when Crosspeace gave the Middleham trainer his 11th success in 15 days - and his 114th of the campaign - in the 'Jock Murray Memorial' Nursery.
Royston Ffrench had the youngster, owned by Favourites Racing, smartly out of stall one and quickly moved him across towards the stands side.
Always at the head of the affairs in this seven-furlong contest, Crosspeace (5-1) stuck on gamely when challenged by Top The Charts in the final furlong. By Martin Kelly, PA Sport
* Catterick's Flat meeting tomorrow is subject to an 8.30 inspection today. The recent heavy rainfall has thrown the fixture into doubt.
