PHILADELPHIA -- Smarty Jones will not run in the Pennsylvania Derby, missing a chance to race in front of a hometown crowd at Philadelphia Park.

Trainer John Servis earlier this month began preparing the Kentucky Derby and Preakness winner to run on Sept. 6. It would have been the 3-year-old colt's first start since his Triple Crown bid fell short in the Belmont Stakes on June 5.

"John has told us that his training since coming off the Triple Crown break has not progressed significantly enough to keep him on track for a start in the Pennsylvania Derby," Hal Handel, chief executive officer at Philadelphia Park, said Monday.

Smarty Jones' future plans are still under discussion.

Smarty Jones, owned by Pat and Roy Chapman, is based at Philadelphia Park. His first two starts were at the track, with his last race there a 15-length romp in the Nursery Stakes last Nov. 20.

A record crowd of 30,000 was possible at Philadelphia Park if Smarty Jones ran. The current record is 28,692, set at the 1983 Pennsylvania Derby.

Birdstone ran down Smarty Jones with a furlong to go in the Belmont, spoiling the colt's bid to become the first Triple Crown winner since Affirmed in 1978.

Despite the one-length loss, Smarty's popularity remains strong. He was recently syndicated in a deal totaling about $48 million, and will stand at stud at Three Chimneys Farm near Midway, Ky., after he retires.

Smarty Jones has won eight of nine career starts with earnings of $7,563,535, including a $5 million bonus from Oaklawn Park for victories in the Rebel Stakes, Arkansas Derby and Kentucky Derby. The leading North American earner is Cigar at $9,999,915.
