Hollendorfer, along with fillies Sky Beauty, Safely Kept and Open Mind, will be honored during hall induction ceremonies Aug. 12 in Saratoga Springs, N.Y. They were chosen by the hall's Contemporary Committee. A Historic Review Committee will announce additional honorees next month.
Hollendorfer has been a mainstay in Northern California horse racing for nearly 30 years. By the start of 2011, his horses had amassed nearly 5,900 race victories and about $120 million in winnings.
He also trained 2010 Eclipse Award winner Blind Luck.
Sky Beauty won 15 of her 21 races, including a sweep of the New York Filly Triple Crown in 1993. The horse, owned by Georgia Hoffman and Allen Jerkens, earned more than $1.3 million.
Safely Kept won the Eclipse Award as the champion filly in 1988 and took the Eclipse Award as champion sprinter the next year for owners Barry Weisbord and Richard Santulli. Safely Kept won 24 of 31 starts and purses of about $2.2 million.
Open Mind, also a 2-year-old in 1988, won the 1988 Breeders' Cup Juvenile Fillies and the New York Filly Triple Crown in 1989. Open Mind, owned by Eugene Klein, won more than $1.8 million in a career that include 11 stakes race wins.
