Dettori Replaced by Atzeni Aboard Stradivarius

One of British racing's most successful partnerships came to an end July 19 with Frankie Dettori being replaced by Andrea Atzeni aboard Stradivarius  for next week's Al Shaqab Goodwood Cup (G1).

The decision to replace Dettori was made by Stradivarius' owner-breeder, Bjorn Nielsen, and marks the latest chapter in the fallout from the public criticism and scrutiny the rider endured both during and after Royal Ascot last month.

Nielsen said: "Frankie Dettori, who has enjoyed a great relationship with Stradivarius and ridden him to many brilliant stakes victories, more than he has any other horse, will by mutual agreement give up the ride to Andrea Atzeni in the Goodwood Cup.

"Frankie remains not only 'the Strad's' biggest fan, but a very good friend and, of course, I look forward to seeing him continue his phenomenal career as one of the greatest big-race jockeys of all time."

Together, Dettori and Stradivarius won 15 Group races, including the Gold Cup (G1) at Royal Ascot three times, the Goodwood Cup (G1) twice, and the Lonsdale Cup (G2) at York's Ebor Festival on three occasions, although they twice faltered in their effort to emulate Yeats by winning a fourth Ascot Gold Cup.

Dettori and joint-trainers John and Thady Gosden initially agreed on the jockey taking a "sabbatical" from his position as main rider after Royal Ascot, during which John Gosden had twice aired significant frustrations and disappointment at rides given by Dettori to his horses, as well as his attitude before and after races.

The ride given to Stradivarius proved a major flashpoint with John Gosden, Nielsen, and Dettori engaging in animated discussion after the 8-year-old finished third in the Gold Cup to Kyprios , having drifted back from his prominent position and then meeting trouble in running before being forced to switch wide in the home straight for a clear run.

Following the defeat, Nielsen told reporters: "You can't blame the horse here."

The day after the Gold Cup, John Gosden said: "Our hero overcomplicated it yesterday and I was clear in my definition of that. I think it's right to say what you think. It's over, it's past, it's finished, and we move on."

Dettori placed the emphasis on Stradivarius' age after the Ascot defeat, saying he did not have the speed of the younger horses and that "it's been a good era for him."

Having been dramatically replaced on the Gosdens' horses on Criterion Stakes day at Newmarket last month, the 51-year-old Dettori outlined how he planned to spend much of July competing abroad while reaffirming his commitment to continue riding until at least the end of next year.

However, less than two weeks after the "sabbatical" was announced, Dettori returned to riding many of the Gosdens' leading horses, including Inspiral , who was beaten at odds of 1-7 in the Falmouth Stakes (G1), and Emily Upjohn , who lines up in Saturday's King George VI and Queen Elizabeth Qipco Stakes (G1), with the universal support of the owners involved.

With Dettori not riding Stradivarius in what may be the horse's final race in the July 26 Group 1, the mount will be taken up by Atzeni, who is unbeaten in three starts on the star stayer.

Nielsen added: "Andrea will be no stranger to Stradivarius as they are undefeated together, winning the 2017 and 2018 Goodwood Cups as well as the 2017 Queen's Vase."

Neither Dettori nor Atzeni could be reached for comment on Tuesday.

Stradivarius is the general 2-1 second favorite for the Goodwood Cup behind 7-4 favorite Kyprios, with Gold Cup second Mojo Star  and Trueshan , winner of the Northumberland Plate on his most recent outing, next in the betting.

Trueshan, who prefers give in the ground, landed last year's Goodwood Cup on soft turf after Stradivarius was a late non-runner. Trueshan drifted out to 6-1 (from 3-1) for this year's race on Tuesday as Britain experienced record-breaking heat and with the Goodwood ground being labeled good to firm, good in places.

However, trainer Alan King indicated he was eager to run Trueshan if the ground was good next week, and added when speaking to the Racing Post's Front Runner: "He did a little bit of work on Saturday and he's going to work on Wednesday. He's exactly where we want him."

Whether Mojo Star lines up is more uncertain, with trainer Richard Hannon planning to speak with owner Kia Joorabchian before making a final decision.

"I don't know what we're going to do yet," Hannon said. "I need to speak with the owner again about it, but I would say at this stage I doubt we're going to run him there."
