The Experimental Free Handicap, published annually by The Jockey Club since 1935, is compiled for a hypothetical race at 1 1/16 miles on dirt. This years weighting committee of racing secretaries once again comprised Frank Gabriel, Jr. of Arlington Park, Michael Lakow of the New York Racing Association and Thomas S. Robbins of the Del Mar Thoroughbred Club.
The committee weighted a total of 87 males and 66 fillies. Eligible for weighting were all two-year-olds of 2004 that finished among the top four in graded or other unrestricted races with an added-value of at least $75,000 or higher, run in the continental United States.
Jay Em Ess Stables Declans Moon (Malibu Moon Vee Vee Star, by Norquestor) won all of his four starts last year, including the Hollywood Futurity, Del Mar Futurity and Hollywood Prevue Stakes, for earnings of $507,300. He was bred in Maryland by Brice Ridgely.
J. Paul Reddam and Susan Roys Wilko (Awesome Again Native Roots (IRE), by Indian Ridge (IRE)) scored an upset win in the Breeders Cup Juvenile before finishing third to Declans Moon in the Hollywood Futurity. A winner of three-of-12 starts and $934,074, Wilko was bred in Kentucky by Ro Parra.
The 126 pounds assigned the co-highweights is a standard top weight for Experimental colts and is equivalent to the assignment shared by last years highweights Action This Day, Cuvee and Rulers Court. Declans Moon and Wilko are weighted two pounds higher than Cash is King LLCs Afleet Alex (Northern Afleet Maggy Hawk, by Hawkster) and Fog City Stables Roman Ruler (Fusaichi Pegasus Silvery Swan, by Silver Deputy).
In the filly division, the 124 pounds assigned Sweet Catomine (Storm Cat Sweet Life, by Kris S.) is equivalent to the assignment on last years highweight Halfbridled. Bred in Kentucky by her owners Marty and Pam Wygod, Sweet Catomine won three of four starts and $799,800 last year. In addition to the Breeders Cup Juvenile Fillies, she won the Del Mar Debutante and Oak Leaf Stakes.
Sharing second-highweight at 117 pounds are Darley Stables Balletto (UAE) (Timber Country Destiny Dance, by Nijinsky II), Derrick Smith and Michael Tabors Sense of Style (Thunder Gulch Save Me the Waltz (IRE), by Kings Lake) and Peter Vegsos Splendid Blended (Unbridleds Song Valid Blend, by Valid Appeal).
Balletto (UAE) won three-of-five starts, including the Matron Stakes, for earnings of $614,000. She was runner-up in both the Breeders Cup Juvenile Fillies and the Matron Stakes. Sense of Style also won three-of-five starts, including the Matron Stakes and Spinaway Stakes, and earned $369,000. Splendid Blended won three-of-four starts, including the Hollywood Starlet Stakes, and banked $327,400.
Among sires of Experimental horses, Yes Its True tops the colts list with three representatives, while Successful Appeal heads the fillies list, also with three representatives. Combining the two lists, Successful Appeal is the leading sire with five representatives, one more than Unbridleds Song. Of the 153 juveniles weighted, 89 were bred in Kentucky, 37 in Florida and four each in Maryland and New York.
The other use of the Experimental rankings is in determining which horses are "dual qualifiers" for the Kentucky Derby. Horses ranked within 10 pounds of the male topweight or who are a champion in another country and have a Dosage Index of 4.0 or less and a Center of Distribution of 1.25 or less are considered the dual qualifiers. These horses have statistically shown that they have a better chance at winning the Derby. Dual qualifiers are indicated below in bold.
