Jason Barkley, who oversaw a large string of horses in Kentucky for trainer Wesley Ward until midway through this year, now has his own six-horse stable at Keeneland. Barkley, 28, also is working the upcoming Keeneland September yearling sale in conjunction with Franklin Ave. Equine, putting together yearling syndicates.“I’m planning on taking on the 2-year-old races next spring,” said Barkley. “Let’s see if I learned anything from Wesley.”
