Mostabshir looks a colt sure to go on bigger and better things following a dominant display on day three of the Dante Festival at York.

An impressive victory on his debut at Kempton in November earned the Shadwell-owned youngster a place in last month’s Craven Stakes at Newmarket with a view to a potential 2000 Guineas bid, but he could finish only fifth of seven runners.

Perhaps as a result, Mostabshir was passed over on this occasion by Shadwell’s retained rider Jim Crowley, who instead elected to partner Wood Ditton runner-up Kathab.

The latter was the 6-4 favourite on the strength of that fine effort behind Thursday’s luckless Dante Stakes third Passenger, but he was ultimately unable to lay a glove on John and Thady Gosden’s highly impressive winner.

With William Buick in the saddle, the son of Dark Angel set his own fractions in front and once asked to go about his business quickly put daylight between himself and his rivals. His stablemate Ziryab finished best of the rest, pipping Kathab to the runner-up spot, but was a full five lengths behind Mostabshir.

Gosden senior said: “He’s like a lot of ours – the grass gallops were closed in Newmarket, so they had to train on the all-weather and then when they went to the races they ran in a bog and he didn’t like it. This was the first summer ground we’ve had this year and it’s a different result.

“William gave him a great ride from the front and said he gave him a lovely feel. What was nice was that William said he quickened twice, and when they do that you’ve got to take note.”

Coral cut Mostabshir to 8-1 from 50-1 for the St James’s Palace Stakes a Royal Ascot, a Group One contest Gosden has previously won with Kingman (2014), Without Parole (2018) and Palace Pier (2020).

The Clarehaven handler was non-committal regarding future plans, though, adding: “He was giving 6lb to the opposition so it was a decent performance, but we’re in a complete muddle now as we don’t know if we’ll go to the Britannia or the handicapper will make it impossible – the other option is to go in at the deep end.

“What he’s shown today is that on genuine summer ground he’s a decent horse.”

Shadwell’s racing manager, Angus Gold, walked into the paddock with a rather puzzled look on his face.

He said: “I’m delighted to see him quicken like that, I didn’t expect it.

“He looked a galloper when he won at Kempton and it didn’t work out for him in the Craven for whatever reason – course, ground, needed the run, whatever.

“William said he quickened twice and under a penalty that was a handy enough performance today.

“Timing-wise you’d love to run him in a Listed race somewhere and if that went well then go St James’s Palace, but there isn’t the time to do it. We’ll have to see how he is and see what John thinks.

“We ran in the Craven to see if he was a Guineas horse, it fell in a hole so we thought we’d come back down to bring him back up but to do that with a penalty in that style – that’s why I was a bit puzzled, I was surprised to see the speed.

“As for Kathab, Jim says he probably needs 10 furlongs, if anything.”
