A turn-up in the Darley July Cup had looked a distinct possibility and it was supplied by 20-1 shot Mayson as he led for virtually all the six furlongs at a saturated Newmarket this afternoon.
It was a first British Group One winner for both trainer Richard Fahey and dual champion jockey Paul Hanagan, who was prostrate on the very same turf two weeks ago after a nasty fall.
The incident was not serious enough to keep Hanagan out of action for more than a few days and the outsider rarely looked in any danger as he galloped past the line five lengths clear of The Cheka.
Mayson had appeared a sprinter of obvious potential when winning twice over the Rowley Mile in the spring but lost his chance in the stalls in the Duke Of York Stakes and was well beaten in a Group Three race at Newcastle a fortnight earlier.
The Hanagan-Fahey axis, not seen as often with the rider now retained by Sheikh Hamdan Al Maktoum, collected the Prix Jean-Luc Lagardere together with Wootton Bassett in 2010.
"It's typical of this game, the ups and downs, so it's been an amazing couple of weeks," said Hanagan.
"It's a big weight off my shoulders. Being the champion jockey, you really need to be winning top-class races like this. It's such a good buzz."
Fahey said: "It's fantastic for me and Paul. They don't realise he's still my number one and we borrow him from time to time!
"We thought he was very good but it went wrong at York when he got his leg stuck in the stalls and it was unraceable at Newcastle - you put your foot on the track and water was coming through. This track has taken the rain fantastic.
"He's in the Nunthorpe, but he got very upset at York in the stalls, so we'll see."
Eve Johnson Houghton, trainer of the second, said: "I'm absolutely delighted. Jimmy (Fortune) said that he loved the ground, but I said I thought that was pushing it, he handled it.
"He just let him bowl along and fair play to the winner, we've beaten him before and he's beaten us. I suspect we will look at Champions Day now."
James Fanshawe is also thinking of Ascot for third-placed Society Rock (7-2 favourite) and said: "When the conditions are like this, I think you are just grateful they have run well."
Australian raider Ortensia ran with credit in fourth and trainer Paul Messara said: "She hated the track, she'd never run on ground anything like that before.
"On that basis it was a huge run and we'll see how we go in the Nunthorpe."
A rugged performance was required from Olympic Glory to reach the top of the podium by a head in the 32Red.com Superlative Stakes.
It was the fourth time the juvenile Group Two has been landed by the Richard Hannon stable, whose runner had posted an excellent second to Dawn Approach in the Coventry Stakes at Royal Ascot.
The 6-4 favourite showed great tenacity by not allowing a late challenge by Birdman to put him off his stride.
Interestingly, jockey Richard Hughes said: "He just missed a few days earlier in the week and blew up a bit in the last 100 yards. He had a problem with his foot but he came back and we were lucky."
Hannon's son, Richard junior, said: "He only just got the seven (furlongs) there and you have to say that the Coventry form looks strong.
"You'd have to start thinking about the Dewhurst and maybe the Vintage Stakes at Goodwood."
Birdman's trainer David Simcock said: "He just got a bit tapped for toe and he'll be running over a mile by the end of the year."
Bonnie Brae provided a glimmer of light in what has been a wretched season for David Elsworth in the 32Red Bunbury Cup.
Quite well-backed at 13-2 despite a poor effort in the Royal Hunt Cup, the mare showed her true colours for Ryan Moore by picking off Captain Bertie and winning by two lengths.
"It's been pretty tough this season. That's my fifth winner and here we are in July," said Elsworth.
"We've had some coughing and their blood hasn't been right, so we've been very quiet.
"She's a tough old sort and I've still got her in the big handicap at Ascot next week. I'll see how she is."
Moore wrapped up the top jockey title at the meeting when Hasopop (7-2) pulled seven lengths away from Godolphin's 1-4 favourite Bircham in a three-runner Rossdales EBF Conditions Stakes.
Trainer Marco Botti will continue to take the colt along slowly.
John Ryan's Ocean Tempest (33-1) scraped home a hair's breadth ahead of Fire Ship and Jake's Destiny in the 32 Red Casino Handicap.
