Pre-sale coverage Sale preview: Keeneland September enters on solid footing Though the format has been tweaked slightly, the 2015 edition of the Keeneland September yearling sale looks much like the one that it preceded. Once again, the 12-day sale will start after a record-setting juvenile sales season and a run of solid performances from the earlier yearling sales on the calendar. Hips to watch Horses to watch during Book 1 of the Keeneland September yearling sale, based on their pedigrees and past auction results of notable family members. The Factor among first-year sires to watch Of the 25 stallions to enter stud in Kentucky in 2013, 16 were Grade 1/Group 1 winners – and, rightfully, they attracted stellar books. Two years later, the resulting foals are adding spice to a resurgent yearling market. Among that standout group of Kentucky’s first-year yearling sires, The Factor was the breakout success story of last month's Fasig-Tipton Saratoga selected yearling sale, the first boutique auction of the yearling calendar. Frankel's five among stars of sale Two-time European Horse of the Year Frankel, an unbeaten 10-time Group 1 winner, is represented by five colts from his first crop at Keeneland September, the first of their kind in the U.S. market. Q&A: Duncan Taylor To say it’s been a big year for the Taylor Made operation would be putting it mildly. Over the past eight months, the operation has seen sales graduate American Pharoah win the Triple Crown, purchased a minority stake in dual classic winner California Chrome, and sold yearlings from the final crop of cornerstone sire Unbridled’s Song. President and CEO Duncan Taylor spoke with Joe Nevills about that and more. Sparkman: Popular sires more prolific than ever The world of Thoroughbred breeding has changed vastly in recent decades. Columnist John P. Sparkman examines how trends have shifted - leading to changes in the commercial marketplace.
