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.
Off the back of that she made it three wins from three for the season when landing the Oaks double at the Curragh, again going on to score by a wide margin.
She is the odds on favourite to take this event and if performing to the same standard as her last few runs then she looks unbeatable.
