Ballydoyle takes the wraps off Derby winner Serpentine's brother at Gowran

The latest chapter of Remember When's astonishing broodmare career is set to continue at Gowran Park on Monday when Aidan O'Brien unleashes the blue-blooded King Of The Castle in the mile maiden.

Second behind Snow Fairy in the 2010 Investec Oaks, Remember When is a three-parts sister to the top-class middle-distance performer Dylan Thomas, the pair being out of Lagrion, a daughter of Diesis who also produced 1,000 Guineas heroine Homecoming Queen and champion two-year-old filly Queen's Logic.

Remember When has been sent exclusively to Coolmore's champion sire since retiring from racing ten years ago – with her first five European runners winning stakes races – and her name hit the headlines when Serpentine struck a major surprise in the Investec Derby earlier this season having only won a maiden at the Curragh a week before.

The colt was also providing the supersire with a record-breaking fifth win in the Epsom Classic, surpassing Sir Peter Teazle, Waxy, Cyllene, Blandford and late studmate Montjeu.

Serpentine was a reasonable fourth in the Qipco Champion Stakes at Ascot on Saturday, while Remember When's other stakes-winning progeny are Wedding Vow, winner of the Kilboy Estate Stakes and second in the Nassau Stakes behind Legatissimo, Group 3 scorer Beacon Rock, Blue Wind Stakes victress and Oaks third Bye Bye Baby, plus the Listed-winning Bound.

King Of The Castle is Remember When's seventh foal, while she also has a yearling colt by Galileo on the ground.
