Having needed her first two runs as a juvenile, she got off the mark at The Curragh at the third time of asking in a Fillies' Maiden.
However, since then she has raced four times between seven furlongs and a mile in decent graded events and has struggled being outclassed.
Stepping up in trip on debut this term brought bring improvement out of her, when winning the Group Three Musidora Stakes at York over 10.5f.
Many thought off the back of that she should have been closer in the market to her stablemate Santa Barbara, and they were right.
Snowfall went on to take the event with ease, winning by a record 16 lengths for Aidan O'Brien and jockey Frankie Dettori and that saw the handler land the event for the ninth time.
She is the big odds on favourite to land the Oaks double and if performing anything like she did at Epsom then she will not be beaten.
