The filly ran fourth in her 3-year-old debut before a trainer change and a second-place finish in the Grade 1 Santa Anita Oaks. Ria Antonia then followed up unplaced tries in the Kentucky Oaks and the Preakness Stakes with a second-place effort in the Iowa Oaks. The filly had a pair of fourth-place finishes over the summer and finished second in the Grade 1 Spinster at Keeneland in October.
Ria Antonia is from the family of Grade 1 winner Behaving Badly.
