Tizdejavu, a winner of four graded turf stakes and nearly $700,000, has been retired to stud at Crestwood Farm. A 2005 foal by Tiznow, the horse will stand for a $5,000 fee in 2011 at the Lexington, Ky., farm. Greg Fox, the equine veterinarian who turned to training in 2005 and sent out Tizdejavu to 8 wins from 16 career starts, said the horse “never really came back to himself” following splint-bone surgery last summer after a three-race win streak that culminated with a front-running triumph in the Grade 2 Firecracker Handicap at Churchill Downs. “At least he went out on the right note.” Bred and owned by Michael Cooper and Pam Ziebarth, Tizdejavu also won the Grade 3 American Turf, the Grade 2 Jefferson Cup, and the Grade 2 American Derby as a 3-year-old of 2008.
