Three juveniles breezed an eighth-mile in 10 seconds Friday as the Ocala Breeders’ Sales Company’s June 2-year-old auction’s three-day preview got underway in Ocala, Fla. The 10-second works were the fastest at the distance. The speedy trio was Hip No. 56, an Unbridled’s Song-Kauai Calls colt; Hip No. 1105, an Exclusive Quality-Mad About Julie filly; and Hip No. 134, a Bernstein-Miss Mambo colt.  Exclusive Quality also had the day’s quickest three-eighths worker, a daughter of Runaway Silver cataloged as Hip No. 233. She went in 33.8 seconds. The day’s fastest quarter-mile workers went in 21.2 seconds. They were Hip No. 18, a Hard Spun-Honeypenny filly, and Hip No. 103, a Montbrook-Lucky Trip colt. Friday’s under-tack session featured Hip Nos. 1-240. The preview was to continue through Sunday with Hip Nos. 241-480 working Saturday and Hip Nos. 481-723 working Sunday. Under-tack sessions take place over the OBS facility’s Safetrack synthetic oval in Ocala. Sessions start at 7:30 a.m.
