Moonstone (horse)

Moonstone was not raced as a two-year-old and began her racing career in a maiden race over ten furlongs at Leopardstown Racecourse on 20 April 2008. Starting the 3/1 joint favourite in a seventeen-runner field she made steady progress in the straight and finished second to the Dermot Weld-trained colt Winchester. Despite her defeat she reportedly displayed "immense potential" and was made ante-post favourite for The Oaks.[6] The filly was then stepped up in class and sent to England for the Musidora Stakes (a trial race for the Oaks) at York Racecourse on 14 May. Racing on good-to-firm ground she tracked the leaders before being outpaced in the straight and finished fourth behind Lush Lashes, Cape Amber and Dar Re Mi.[7]

Moonstone was a member of a six-horse Ballydoyle contingent for the 230th running of the Oaks at Epsom Racecourse on 6 June and with Johnny Murtagh, who had ridden her in her first two starts, opting to partner Adored, she had Richard Hughes in the saddle.[8] She was made a 25/1 outsider but after being restrained at the rear of the field in the early stages she stayed on strongly in the straight to finish second to Look Here with the favoured Lush Lashes back in fifth. Murtagh was back in the saddle when Moonstone started 2/1 favourite for the Irish Oaks at the Curragh Racecourse on 13 July. The better fancied of her thirteen opponents included Katiyra (winner of the Derrinstown Stud 1,000 Guineas Trial and third in the Epsom Oaks), Gagnoa (Prix Penelope, second in the Prix de Diane), Mad About You (second in the Irish 1,000 Guineas) and Chinese White. After racing just behind the leaders before moving into second place behind Ice Queen, a 66/1 outsider also trained by Aidan O'Brien, inside the last quarter mile. Despite her odds, Ice Queen showed no signs of weakening and it was only in the final strides that Moonstone overhauled her stablemate to win by a short head. Gagnoa was two lengths back in third place ahead of Chinese White at Katiyra.[9] She became the first maiden to win the race since Olwyn in 1977 and gave O'Brien his seventh consecutive Irish classic winner.[10] Aiden O'Brien commented "It was a great race with two jockeys and two fillies giving it their all. It was a usual masterful ride from Johnny... Moonstone ran a smashing race at Epsom and she stays very well. She is progressing well".[11]

After an absence of almost three months, Moonstone returned for two races at Longchamp Racecourse. In the Prix de l'Opéra over 2000 metres on 5 October she made no impact as she finished twelfth behind the German filly Lady Marian. Three weeks later she was moved up in distance and matched against male opponents in the 3100 metre Prix Royal-Oak and produced a rather better effort, coming home sixth of the eleven runners, four and a half lengths behind her stablemate Yeats.[12]
