Fastnet Rock has sired his second northern hemisphere G1 winner with the Aidan O’Brien-trained filly Diamondsandrubies taking out the Pretty Polly Stakes at the Curragh on Sunday.


Diamondsandrubies Horseform (Fastnet Rock x Quarter Moon by Sadler’s Wells) is the 21st G1 winner overall for Fastnet Rock, who will be crowned Australia’s champion sire for the third time this season. The Danehill stallion did not make the trip up from Coolmore’s base in Australia for the northern hemisphere breeding season this year for the first time since 2010.

Diamondsandrubies is the second G1 winner in the UK and Ireland for Fastnet Rock this month, joining his stablemate Qualify who won the Oaks at Epsom.

Qualify beat 10000 Guineas winner Legatissimo  in the Oaks and that filly by Danehill Dancer again came off second best when she just failed to run down Diamondsandrubies at the Curragh.

Winner of the Cheshire Oaks earlier this season, Diamondsandrubies was unlucky in the Oaks at Epsom when she suffered interference when finishing fourth.

Diamondsandrubies is out of the Sadler’s Wells mare Quarter Moon, who won the G1 Moyglare Stud Stakes at two before finishing second in the Epsom Oaks and Irish Oaks for O’Brien.

The 16-year-old mare has produced seven winners including You’ll Be Mine, who was second in the G1 Fillies’ Mile, and G3-placed Born To Be King.

Quarter Moon is one of seven winners out of Jude, a daughter of Darshaan. They include Irish 1000 Guineas winner Yesterday and Oaks third All My Loving.

Diamondsandrubies has a two-year-old sister named How High The Moon, who is in training with O’Brien and who is entered to run in a maiden at Tipperary on Thursday.

• IMPOSING Irish Derby winner Jack Hobbs  is the fourth G1 winner and 53rd stakes winner for his now pensioned sire Halling.

Halling was retired from full time service at Dalham Hall Stud in Newmarket in 2013 at the age of 22 after the son of Diesis had covered for 17 consecutive seasons including a stint standing at Emirates Stud in Dubai.

Jack Hobbs is his fourth G1 winner joining Grand Prix de Paris winner Cavalryman, Prix Ganay winner Cutlass Bay and Preis von Europa winner Empoli.

His trainer John Gosden also trained Halling.

Purchased by Blandford Bloodstock for 60,000gns from the draft of Minster Stud at the Tattersalls October Yearling Sale Book Two, Jack Hobbs is from the US winner Swain’s Gold, a daughter of Swain,

Bred by by former champion jockey Willie Carson, Jack Hobbs is the fifth foal from Swain’s Gold, also producing the triple winner Mrs Greeley and Niceofyoutotellme, winner of the Suffolk Handicap at Newmarket last year.

Swain’s Gold is out of the Don’t Forget Me mare Golden Pond, a G2 winner at Gulfstream Park and a half-sister to the dam of May Hill Stakes winner Pollenator.

Swain’s Gold has a two-year-old colt by Equiano, a yearling colt by Mayson and a filly foal by Australia’s Golden Slipper winner Sepoy.

Jack Hobbs is the fourth Tattersalls sold winner of the Irish Derby in five years and the first British-trained winner of Ireland’s premier classic since 1993.
