Six weeks after a record 16-length win in the Group 1 English Oaks, Snowfall won Saturday’s Group 1 Irish Oaks at The Curragh by only 8 1/2 lengths. No matter the margin, Snowfall’s impressive win on Saturday left her at the fore of the future-book market for the Prix de l’Arc de Triomphe in Paris in October. Snowfall (who paid $2.80 in American pools) closed from fifth in field of eight under jockey Ryan Moore, who had to briefly wait for racing room with about a half-mile remaining in the $472,200 Irish Oaks at 1 1/2 miles. Snowfall responded quickly when space developed to pull clear through the stretch. The win confirmed Snowfall’s dominance of the European 3-year-old filly division and stretched her unbeaten streak to three races this year. Prior to the English Oaks on June 4 at Epsom Downs, Snowfall won the Group 3 Musidora Stakes at 1 5/16 miles by 3 3/4 lengths on May 12 at York Racecourse in England. Snowfall was trainer Aidan O’Brien’s record-equaling sixth win in the Irish Oaks, Ireland’s top race for 3-year-old fillies. O’Brien won the Irish Oaks for the first time in 2006. Snowfall was his first winner since Seventh Heaven in 2016. British-based Michael Stoute also has won the Irish Oaks six times. The O’Brien family swept the superfecta in the Irish Oaks. The Aidan O’Brien-trained Divinely and Willow finished second and fourth, while Nicest finished third for O’Brien’s son, Donnacha. Snowfall, a Japanese-bred filly by Deep Impact, races for the Coolmore partnership and has won 4 of 10 starts. At 2, she was largely a disappointment, winning once in seven starts. Snowfall was fourth, fifth, ninth, and eighth in group stakes in England and Ireland from early August to early October last year. Aidan O’Brien said after the Irish Oaks that Snowfall will make her next start in the Group 1 Yorkshire Oaks at York Racecourse at 1 1/2 miles on Aug. 19. The Group 1 Arc de Triomphe’s, Europe’s leading flat race, is run at 1 1/2 miles at Longchamp Racecourse in Paris on Oct. 3.
