One trainer, one jockey, one horse and one race to follow on Saturday

Trainer

Not many trainers have top-flight runners in three countries on the same day, but not many trainers are Aidan O'Brien, who is represented at the highest level in Britain, France and the US.

He runs two fillies in Newmarket's Kingdom Of Bahrain Sun Chariot Stakes (I Can Fly and Hermosa) and the Qatar Prix de Royallieu (Delphinia and South Sea Pearl) at Longchamp.

Saturday cards

Unhelpfully for the Ballydoyle ace, those races are due off at 3.25, but the trainer has time to recover before Just Wonderful runs in the First Lady Stakes (10.04) at Keeneland, where stablemate Van Beethoven is in action in the Shadwell Turf Mile Stakes (11.15).

Jockey

William Buick attempts to get his weekend off to a flyer with some promising rides at Longchamp, including aboard Line Of Duty.

The three-year-old is a likely favourite for the Group 2 Qatar Prix Dollar (12.30) after finishing third behind Circus Maximus and Romanised in the Prix Du Moulin last month.

Buick should also be in contention aboard the Charlie Appleby-trained Moonlight Spirit in the Group 2 Qatar Prix Chaudenay (4.00).

Horse

Dee Ex Bee bids to record his first Group 1 victory in the Qatar Prix du Cadran (4.35).

The Mark Johnston-trained four-year-old, who finished behind star stayer Stradivarius in his last three starts, will face nine rivals, including last year's winner Call The Wind and the consistent Way To Paris.

He will be partnered by French jockey Mickael Barzalona for the first time, with Silvestre de Sousa, on board for his last four starts, in action at Ascot with rides for King Power Racing.

Race

Enbihaar, winner of the Group 2 Park Hill Stakes, steps up to the highest level for the first time in the Qatar Prix de Royallieu (3.25).

She attempts a four-timer for John Gosden, who is also represented by Oaks winner Anapurna, the mount of Frankie Dettori, and the Buick-ridden Lah Ti Dar.

The nine-runner field also includes the Andre Fabre-trained Musis Amica, second to Star Catcher in a Longchamp Group 1 last time.
