The inaugural running of the event was on 6 July 2002 as the American Oaks Invitational at Hollywood Park Racetrack in Inglewood, California with a purse of $500,000.

[1] The following year, 2003, with a purse increase to $750,000 the winner was the Irish-trained filly Dimitrova who had previously run third in the Irish 1,000 Guineas.

Entrants in the first time the event held Grade I status included fillies from Great Britain, Ireland, France, New Zealand and Japan.

[5] Cesario became the first Japanese-bred and Japan-based racehorse in nearly a half-century to win a US stakes race (Hakuchikara won the Washington's Birthday Handicap at Santa Anita in 1959 upsetting US champion Round Table).

Jockey Garrett Gomez stalked the early pace set by Attima (GB) and made a sweeping three-wide move around the second turn, clearing the field under mild left-handed urging.

The 2011 running of the event produced a dead-heat between Nereid and Cambina which was the first in a Grade I at Hollywood Park since the Richard Mandella-trained pair of Beautiful Melody and Reluctant Guest finished on even terms in the Beverly Hills Handicap on June 30, 1990.

† In the 2002 inaugural running, Dublino was first past the post but was disqualified for interference in the straight and Megahertz (GB) was declared the winner.
