Derby hero's brother just one of several intriguing newcomers on Saturday

There are several eyecatching newcomers in Ireland and Britain on Saturday but there’s only one place to start and that’s with last year’s Derby winner’s brother.

Serpentine and Emmet McNamara took the bull by the horns at Epsom last summer, making every yard to win by five and a half lengths, and it wasn’t their fault that other jockeys were a little asleep at the wheel, albeit that’s not to say Serpentine was not simply the best horses on the day.

He started at 25-1 - a considerably shorter price than Torquator Tasso in the Arc - and it was certainly not the biggest shock in the Derby, far from it.

At Leopardstown on Saturday his little brother Downing Street, likewise trained by Aidan O’Brien for the Coolmore partners, sets out on his journey in the mile maiden (2.05).

By Galileo, of course, the two-year-old colt is out of Danehill Dancer’s daughter Remember When, who was runner-up in the Oaks, and along with Serpentine is also a full sibling to Group 2 winner Wedding Vow, Group 3 scorers Beacon Rock and Bye Bye Baby and Listed winner Bound.

In the same race, the master of Ballydoyle introduces another two-year-old colt by Galileo in Realism, who is also out of a daughter of Danehill Dancer, this time in the form of Where. He is a brother to Irish Oaks runner-up Rain Goddess.

Another making his debut is Point King, by another late Coolmore sire in Zoffany and out of a daughter of Galileo in Loved. The dam was not much cop on the track, winning a maiden from five starts, but is a sister to Group 2 winner Battle Of Marengo. Point King is trained by Joseph O’Brien.

O’Brien jnr happens to have the juvenile to beat in the contest, another by Zoffany out of a Galileo mare (Round Of Applause), the dual runner-up Good Heavens, who is a McManus homebred.

The opening fillies’ maiden at 1.30, also over a mile, is no less intriguing. It will also take much more winning, with a handful already having shown promise.

Standing out among the newcomers is the Aidan O’Brien-trained Emily Dickinson, being a daughter of Chicquita, who of course cost a record €6 million at the Goffs November Mares Sale in 2013.

The daughter of Montjeu and winner of the Irish Oaks has produced this year’s Irish Oaks third Nicest, to American Pharoah, and the Group-placed maiden winner Secret Thoughts, by War Front.

Emily Dickinson is by Dubawi and looks an exciting addition to the racing family.

Alluringly’s half-sister Trustworthy also makes her debut for the Coolmore partners in this race, representing the Donnacha O’Brien yard, while the Aga Khan’s homebred Zaniyka also catches the eye.

By Siyouni out of Azamour’s daughter Zannda, a Group 3 winner, Zaniyka is trained by Demot Weld.

Ken Condon, meanwhile, introduces a half-sister to none other than Authorized, winner of the Racing Post Trophy when it was run at Newbury, the Dante, Derby and Juddmonte International, and who now stands at stud in Turkey.

The filly in question, Accomplished, is by Mastercraftsman, who sadly died in August aged 15, whereas Funsie's first foal Authorized was by Montjeu.

The Niarchos family has a couple of three-year-old newcomers to look forward to on Saturday, a filly at Leopardstown and a colt at Wolverhampton.

The former, Valle De La Luna, contests the 1m2f maiden at 4.20. By Galileo, she is out of that fine racemare Fiesolana, winner of the Group 1 Matron Stakes in the Niarchos silks after being picked up for 960,000gns at the Tattersalls December Mares Sale in 2013. She also won eight other races.

Fiesolana’s best runner to date has been Listed winner Up Helly Aa, by Galileo. Valle De La Luna is with Jessica Harrington.

Making his debut in a 1m11/2f novice event at Wolverhampton at 7.30 is Atacama Desert, a colt by Galileo out of Pivotal’s daughter Ikat.

The mare’s best progeny to date has been the superb Main Sequence, by Aldebaron and whose four Grade 1 wins in the United States were capped by the Breeders’ Cup Turf.

If his half-brother is wound up for his debut by Sir Michael Stoute he should go close, albeit novice and maiden events at Wolverhampton can take a bit of winning, and the Gosdens’ Lingfield winner Emblem Empire, a son of Gleneagles, sets a fair standard.
