ケンタッキーオークス
A prime reason for favouring the National Triple Tiara is that the Kentucky Oaks is the most popular races for fillies and draws one of the biggest crowds of any stakes races throughout the year (behind only the Kentucky Derby and the Preakness Stakes). The Kentucky Oaks consistently outdraws the Belmont Stakes, the Travers Stakes and the Breeders' Cup series. On the other hand, the George E. Mitchell is currently only a Grade II race as few modern trainers are willing to race their fillies with only two weeks rest after the Kentucky Oaks. But champion filly Silverbulletday did it in 1999, proving that it is still able to be done.
