Alex Zacney, 19, became part of racing history as the namesake for Afleet Alex, the 2005 Preakness and Belmont Stakes winner. He hoped to add to that after he and his father, Chuck, joined Leonard Green’s D.J. Stable to own Jaywalk, the Eclipse Award winner as the top 2-year-old filly in North America, and promising 3-year-old Maximus Mischief, owned in partnership with Glenn Bennett’s LC Racing.
