James Doyle's much-publicised debut as Prince Khalid Abdullah's new retained rider went off without a hitch as next year's 2000 Guineas favourite Kingman made a second successful visit to the racecourse in the Group Three Solario Stakes at Sandown.

Kingman's Classic odds were shortened again, to a general 5-1 but to just 4-1 with Coral, with a truer examination of his position as a future star of the turf likely to happen in the Dewhurst Stakes on October 12.

Doyle settled the 2-7 favourite in behind his three rivals before accelerating to the lead with more than a furlong (200m) to go and Kingman maintained his advantage until he was eased down close to the line.

"I don't think relief is the right word, I'm happy, he was good," Doyle said.

"He had a big reputation but he did it nicely.

"It's very early stages in his career but he has got all the right qualities to suggest he can progress."

The appointment of Doyle came as a surprise on Thursday and means a few blue-chip names will lose opportunities.

Abdullah's racing manager Teddy Grimthorpe said the prince was pleased to have James as his retained rider.

""We've had great relationships with Ryan Moore, William Buick and Tom Queally and I know trainers prefer to use their own jockeys, but Prince Khalid is pleased to have James and the trainers have been very supportive," he said.

"Hopefully the Juddmonte flag will keep flying for some time."
