On Saturday, Aidan O'Brien-trained runners filled the top three finishing positions in the Entenmann's Irish Two Thousand Guineas (Ire-I). 16-1 longshot Imagine completed the Irish Guineas double for the conditioner at the Curragh Sunday, winning the Entenmann's Irish One Thousand Guineas (Ire-I) under jockey Seamus Heffernan. 9-2 favorite Crystal Music was second in the 16-horse field, two lengths behind the winner. All told, O'Brien's runners took five of the top six finishing positions in the two races, with his Toroca coming home third in Sunday's race. O'Brien-trained Sequoyah came home fourth in the 16-horse field.For O'Brien's top jockey Mick Kinane the weekend was a disappointment. Given his choice of the O'Brien horses, Kinane's mounts finished third in both heats.Based on pedigree, it would be hard to pass over Imagine (Sadler's Wells--Doff the Derby, by Master Derby), a half-sister of Epsom Derby (Eng-I) and King George VI and Queen Elizabeth Diamond Stakes (Eng-I) winner Generous (by Caerleon). Like Imagine, Generous is male-line descendant of Northern Dancer. Imagine is also a full sister to Derrinstown Stud One Thousand Guineas Trial winner Strawberry Roan. Imagine is owned by Mrs. John Magnier and was bred in Ireland by Barronstown Stud and Orpendale.The win marks the first as a 3-year-old for Imagine, who improved her career mark to three wins from nine starts. Prior to Sunday's Guineas triumph, she finished third under Kinane in the Entrepreneur E.B.F. Athasi Stakes and second in the Leopardstown One Thousand Guineas Trial Stakes. Rose Gypsy, the runner up in the Athasi Stakes, went on to win the French One Thousand Guineas (Fr-I). As a juvenile, she won the C.L. Weld Park Stakes (Ire-III) and finished second in the Owen Brown Rockfel Stakes (Eng-II).Imagine completed the mile in 1:41.10 on a good to yielding course.
