Vault, a half-sister to G1W Mirth, was privately purchased in December of 2019. Already a stakes winner, Vault turned in some promising performances in 2020 before turning it up a notch in 2021 when taking her first graded stakes race under a hand ride in the G2 Ruffian at Belmont Park. She was sold for $850,000 at the 2021 Keeneland November Sale.
