Uncle Mo, last year’s champion 2-year-old male and undefeated winner of the Grey Goose Breeders’ Cup Juvenile, received the high weight assignment of 128 pounds on the 2010 Experimental Free Handicap, released today by The Jockey Club and available within the Publications and Resources section of jockeyclub.com.

The filly division is headed by last year’s champion 2-year-old filly and undefeated Grey Goose Breeders’ Cup Juvenile Fillies winner, Awesome Feather, at 123 pounds.

The Experimental Free Handicap, published annually by The Jockey Club since 1935, is a weight-based assessment of the previous year’s leading 2-year-olds, with the weights compiled for a hypothetical race at 1 1/16 miles on dirt. This year’s weighting committee of racing secretaries was composed of Ben Huffman of Churchill Downs, P.J. Campo of the New York Racing Association and Thomas S. Robbins of the Del Mar Thoroughbred Club.

The committee weighted a total of 99 males and 92 fillies. Eligible for weighting were all 2-year-olds of 2010 that finished among the top four in graded or listed stakes races run in the continental United States. Listed stakes in 2010 were those with a value of $75,000 or more available to all starters, and no restrictions other than age or sex.

Uncle Mo (Indian Charlie – Playa Maya, by Arch) won all three of his starts last year by a combined 23 ¼ lengths for earnings of $1,296,000. Owned by Repole Stable, Uncle Mo won the Champagne Stakes in addition to the Breeders’ Cup Juvenile. He was bred in Kentucky by D. Michael Cavey DVM.

The 128 pounds assigned to Uncle Mo is 2 pounds above the standard impost for top Experimental colts, including last year’s co-high weights Lookin At Lucky and Vale of York (IRE). It is the highest assignment since Favorite Trick received 128 pounds in 1997.

Uncle Mo is weighted 5 pounds higher than To Honor and Serve (Bernardini – Pilfer, by Deputy Minister), a winner of three of his four starts in 2010, including the Remsen Stakes and Nashua Stakes. He earned $264,640 for owner Live Oak Plantation.

Boys At Tosconova (Officer – Little Bonnet, by Coronado’s Quest), winner of the Hopeful Stakes and runner-up in the Breeders’ Cup Juvenile, is weighted at 122 pounds. He won two of his four starts on the year and earned $562,060 for his owners Jay Em Ess Stable, Hot Racing Stable LLC, R. Hale Jr., T. Cady, and D. Kanakaris.

At 121 pounds are Comma to the Top (Bwana Charlie – Maggies Storm, by Stormy Atlantic) and Pluck (More Than Ready – Secret Heart (SAF), by Fort Wood).

Comma to the Top won six of his 10 starts in 2010, including the CashCall Futurity, Generous Stakes and Real Quiet Stakes, for owners Gary Barber, Roger Birnbaum and Kevin Tsujihara. He earned $551,600.

Team Valor International’s Pluck won three of his five starts last year, including the Breeders’ Cup Juvenile Turf and the Summer Stakes, and earned $725,440.

In the filly division, the 123 pounds assigned to Awesome Feather (Awesome of Course – Precious Feather, by Gone West) is the standard impost for top Experimental fillies and equivalent to the assignment on last year’s co-high weights, Blind Luck and She Be Wild.

Bred in Florida by her owner Jacks or Better Farm Inc., Awesome Feather’s six victories in 2010 came by a combined 25 ½ lengths. In addition to the Breeders’ Cup Juvenile Fillies, she won the J J’sdream Stakes, Florida Stallion My Dear Girl Stakes, Florida Stallion Susan’s Girl Stakes and Florida Stallion Desert Vixen Stakes. She earned $1,495,746.
