Fancy Blue (foaled 2 February 2017) is an Irish Thoroughbred racehorse. She showed considerable promise as a juvenile in 2019 when she won both of her races including the Listed Staffordstown Stud Stakes. In the following year she finished second in the Irish 1,000 Guineas before winning the Prix de Diane and Nassau Stakes. Background Fancy Blue is a bay filly with a white blaze and a white socks on her hind legs bred in Ireland by the Coolmore Stud. She is owned by the Coolmore partners Michael Tabor, Susan Magnier and Derrick Smith. Like many Coolmore horses she was sent into training with Aidan O'Brien at Ballydoyle. She was from the ninth crop of foals sired by Deep Impact, who was the Japanese Horse of the Year in 2005 and 2006, winning races including the Tokyo Yushun, Tenno Sho, Arima Kinen and Japan Cup. Deep Impact's other progeny include Gentildonna, Harp Star, Kizuna, A Shin Hikari, Marialite and Saxon Warrior. Fancy Blue's dam Chenchikova showed modest racing ability, winning a maiden race on her debut but failing to win in five subsequent starts, but did better as a broodmare, producing several other winners including Smuggler's Cove (Star Appeal Stakes) and Casterton (Prix Lord Seymour). She was a full-sister to High Chaparral. Racing career 2019: two-year-old season Fancy Blue made her racecourse debut in a maiden race over seven furlongs at Naas Racecourse on 18 September and went off at odds of 6/1 in a fifteen-runner field. Ridden by her trainer's son Donnacha O'Brien she raced in mid-division before staying on strongly to overtake the favourite Chasing The Dawn in the closing stages and win by half a length. On 13 October the filly was moved up in class and distance for the Listed Staffordstown Stud Stakes over one mile on soft ground at the Curragh and started the 4/1 third choice in the betting behind A New Dawn (runner-up in the Weld Park Stakes) and Auxilia. With Seamie Heffernan in the saddle she started slowly but produced a sustained run from the rear of the field in the last quarter mile to win by a head from A New Dawn after taking the lead in the final strides. After the race Aidan O'Brien admitted that Donnacha O'Brien had been handling the filly at Longfield stable, near Goold's Cross, County Tipperary and added "She's a quality filly and Seamus gave
