James Doyle called up to replace Ryan Moore on unbeaten Diego Velazquez in Group 1 Futurity at Doncaster

With no Ryan Moore to rely on Aidan O’Brien has asked James Doyle to deliver the knockout ride on the unbeaten Diego Velazquez in the final Group 1 showdown of the season at Doncaster on Saturday.

Big wins on Warm Heart in the Yorkshire Oaks and the Prix Vermeille have persuaded O’Brien to turn to Doyle again in the Kameko Futurity Trophy Stakes in the absence of the suspended Moore.

But among those standing in the way of the Derby second favourite is Ancient Wisdom, supplemented for the race on Monday at a cost of £17,500 and rated a “very strong contender” by trainer Charlie Appleby.
