A trio of intriguing juvenile races with some well-bred prospects caught my eye coming up on Friday. Races from Belmont Park, Churchill Downs and Santa Anita Park highlight the action of the youngsters who could be our stars of tomorrow. CHURCHILL DOWNS Race 1 This five-furlong dash on the main oval attracted a field of eight. Steve Asmussen has unveiled a few sharp juveniles already in 2019, and he has two in this field with one of particular interest to me. Green Destiny (#2) (7-2) is out of a stakes winner who is a half-sister to 2015 Las Virgenes Stakes (G1) heroine Callback. The third dam of the Super Saver filly is the A.P. Indy mare Supercharger, the dam of 2010 Kentucky Derby (G1) hero Super Saver! Also in the cast is Frank’s Rockette (#6) (8-1), who is from the family of two-time champion Indian Blessing, as well as the Ian Wilkes-trained Emily’s Oasis (#8) (4-1), a daughter of Triple Crown star American Pharoah from the family 1991 Kentucky Derby (G1) victor Strike the Gold. BELMONT PARK Race 7 A cast of seven two-year-old colts and one filly will speed five-eighths on the green. Invader (#1) (5-2) draws inside for conditioner Wesley Ward. The $500,000 yearling purchase is a full brother to 2018 Summer Stakes (G1) winner Fog of War. The Kentucky-bred will have Irad Ortiz Jr. at the controls. Kokokomo (#3) (5-1) makes his second lifetime run for Todd Pletcher. The son of Uncle Mo gets blinkers and has room for improvement coming from South Florida. His dam, the A.P. Indy mare Vuemont, is a full sister to two-time Canadian champion Marchfield. Stuart Janney III’s homebred Cloudbased (#4) (8-1) is a half-brother to 2012 Maker’s 46 Mile (G1) victor Data Link. The Orb colt is bred to be a good one who could thrive on the turf. SANTA ANITA PARK Race 2 Unchain Her Heart (#1) (5-2) makes her first appearance for Brian Koriner in this 4 1/2-furlong sprint for California-bred/-sired fillies. The Shackleford filly was a $140,000 Barretts yearling buy who is cut out to be a runner. The bay is out of the winning Doneraile Court mare Courting Elaine, who is a half-sister to three stakes winners including the sublime Wise Dan who earned 11 Grade 1 wins topped by tallies in the 2012 and 2013 Breeders’ Cup Mile (G1).
