The Willard L. Proctor Memorial Stakes was an American Thoroughbred horse race run annually in late May at Hollywood Park Racetrack in Inglewood, California.
Open to two-year-old horses, it was contested on dirt over a distance of five and one half furlongs.
The event offered a purse of US$75,000 added plus a $22,500 bonus for horses bred in the State of California.
Inaugurated in 1953 as the Westchester Stakes, for that first year only it was restricted to fillies.
There was no race in 1983 and in 1984 it reverted to its original Westchester Stakes title until 2000 when it was renamed to honor for long-time California trainer Willard L. Proctor who died in 1998.
