As the under-tack preview show for the Ocala Breeders’ Sales Co.’s spring sale of 2-year-olds in training continues its weeklong run, the leaderboard remains crowded. Through five of seven sessions, 24 juveniles by 22 different sires share the bullet 9 4/5-second time for a furlong on the Ocala Training Center’s all-weather Safetrack. The only stallions represented by multiple juveniles in the group are Maximus Mischief and Yaupon, the latter among this year’s freshman sires. Maximus Mischief has colts consigned by Cardozo's Brothers and Grassroots Training and Sales, respectively, in this group. Yaupon’s bullet furlong workers are a colt consigned by de Meric Sales and a filly consigned by Pick View. They are joined by colts by By My Standards, Complexity, Essential Quality, Galilean, Into Mischief, Leinster, Shancelot, and Win Win Win; and fillies by Army Mule, Authentic, Curlin, Good Magic, Justify, Kantharos, Munnings, Not This Time, Rock Your World, Temple City, Tiz the Law, and Upstart. Yaupon also has a filly who shares the fastest quarter-mile time, 20 3/5 seconds, with a Mitole filly and an Independence Hall colt. :: Access the most trusted data and information in horse racing!
