Moore has landed the ride on Society Rock, winner of last year’s Golden Jubilee Stakes, while Luke Morris will be aboard Krypton Factor and Jimmy Fortune takes the mount on The Cheka.
Society Rock, trained by James Fanshawe, was beaten just half a length on his return to action in the Duke of York Stakes and was then an unlucky fifth behind Black Caviar in the Diamond Jubilee Stakes.
Moore has never ridden the horse before and is an unusual booking for the Newmarket trainer, who has only used him 10 times in the last five seasons.
Fanshawe’s wife Jacko tweeted: “Ryan Moore will be on Society Rock when he runs in the July Cup on Saturday. James happy he wants to ride him and he seems in good form.”
Luke Morris is delighted to have picked up the ride on Krypton Factor for Bahrain trainer Fawzi Nass as Kieren Fallon is needed by Luca Cumani at York.
Krypton Factor was just a head behind Society Rock behind Black Caviar in the Diamond Jubilee.
“Fingers crossed the rain stays away for him,” Morris told At The Races.
“He likes decent ground and I hope it will dry out for Saturday.
“It was a bit of a surprise. He is Kieren Fallon’s ride and he’s off to York to ride for Mr Cumani so it’s nice to get the opportunity to ride him.
“He beat Rocket Man in Meydan and any horse that can do that is special. He’s rated 124 and those are the horses you want to be getting on.”
The Cheka may have been another six lengths behind those two in 12th at Royal Ascot but his trainer Eve Johnson Houghton felt her stable stalwart was below his best that day.
“He seems in really good form after Ascot. I thought he ran below par there but I can’t find a reason for it,” said the Blewbury trainer.
“We did some tests and he’s absolutely tickety boo, so I’m hoping it’s just one of those things.”
Meanwhile Irish trainer David Nagle is one person who does not want the weather to take a sudden turn for his improving sprinter Maarek.
The five-year-old has won four of his last six starts, including a handicap at Newmarket and the Chipchase Stakes at Newcastle, as well as finishing a close sixth under a big weight in the Wokingham.
He is coming back over to England for the chrisbeekracing.com Stakes (registered as the Hackwood Stakes) at Newbury and conditions look like being ideal once more for the soft-ground lover.
“We think this weather is beautiful!” said Nagle.
“I’m driving the box now on the way to Newmarket and we’ll go on to Newbury from there.
“He’s in good form and he’s taking his races well, obviously we hope it’s soft.
“It was desperate at Newcastle and he coped, he’s a completely different horse in those conditions and Newcastle was probably his easiest win.
“He ran well on good ground at Ascot but relishes it soft.
“I think we’ve got Paul Hanagan to ride him as Graham Lee is required at Newmarket. It’s disappointing having to change jockeys again but it’s one of those weeks. Anyway, he’s not a bad replacement, is he?”
