Female jockey, Georgina Sergeon. - Colin Hamilton

The apprentice riders who graduated from the Jockeys' School in August and started riding at Caymanas Park on September 3, have begun to make an impact.

On Saturday, they not only won the last five races on the 10-race programme, but accounted for the co-features as well - the Royal Dad Trophy and the inaugural running of the Impulse Jamaica (Energy Drink) Sprint.

Among the winners was the lone female apprentice Georgina Sergeon, who rode a copybook race aboard 5-2 chance SATAN'S RULE for champion trainer Wayne DaCosta in the seventh race for native and imported three-year-olds over 1200 metres.

This marked the second win of her career, having booted home 9-2 chance NAVAJOJOE on Saturday, September 12 to record her maiden win, becoming only the second Jamaican woman since Azel Cowie aboard HEARTEASE in January, 1992 to ride a winner at Caymanas Park.

Sergeon pushed SATAN'S RULE to the front in the early stages in the 13-strong field. After turning for home three lengths clear of odds-on favourite MARSHALL JIM, SATAN'S RULE, under a determined ride from the 18-year-old, kept on strongly to stave off the fast-finishing PLATINUM VALLEY (22-1) by a length.

Significantly, the claiming apprentices swept the four places in this race, as the runner-up was ridden by Aaron Chatrie, while Jodeien Anderson was aboard the third horse, CHINA CROSSING and the very promising Doushane Gordon aboard the grey MARSHALL JIM in fourth.

In the closing race for the Impulse Sprint Trophy, the apprentices were at it again, sweeping the first five places (hi-five). This was won by 7-1 chance CLASSIC BEAU, ridden in post-to-post fashion by young Anderson for trainer Richard Azan.

Fellow apprentice Richard Mairs rode two winners on the card in ROYAL BLAST (8-1) and the vastly improved SPACE FURY (4-5 fav) for trainer Fitzroy Glisepie in the Royal Dad Trophy race over 1820 metres.

Mairs has now ridden nine winners, one less than Doushane Gordon who was aboard eighth race winner MEDUSA.
