Carpe Diem, a multiple Grade I winner who won the 2015 Toyota Blue Grass Stakes at Keeneland, has been retired from racing because of an injury.
The horse has a chip in the lower joint of his right knee, Stonestreet Stables and WinStar Farm announced Thursday.
He will stand stud at WinStar in 2016.
Carpe Diem has not raced since finishing 10th in this year's Kentucky Derby. The son of Giant's Causeway had only posted two workouts since late May with the most recent being a four-furlong move in 48.77 seconds at Saratoga on July 12.
Never miss a local story.
"Carpe Diem is as good as any young horse WinStar has ever been involved with, and it's always bittersweet when you retire a colt of his quality, particularly knowing we likely never got to see his best," WinStar Farm President and CEO Elliott Walden said. "The positive is that he is an extremely exciting stallion prospect.
Walden said Carpe Diem was in perfect position in the Kentucky Derby, "but when he switched leads going into the far turn I felt something wasn't right," Walden said.
Carpe Diem did not run in the final two legs of the Triple Crown — the Preakness and Belmont.
Walden said the chip revealed itself as Carpe Diem was being prepared for a planned return in the Haskell Invitational at Monmouth Park on Aug. 2.
A $1.6 million sale topper at last year's OBS March sale, Carpe Diem lived up to his reputation in his 2-year-old debut at Saratoga, overcoming the rail post position to draw away to a 2½ -length win. The chestnut colt captured the Grade I Breeders' Futurity at Keeneland in his second career start and capped his juvenile campaign with a runner-up finish in the Breeders' Cup Juvenile.
"The impressive thing about Carpe Diem, to me, is his ability to run 5½ furlongs in a tough maiden race at Saratoga and then stretch out to win Grade I races around two turns," trainer Todd Pletcher said. "It is unfortunate his career ended so soon because I feel like he had more Grade I wins in him."
Carpe Diem started his 3-year-old campaign in Florida, where he scored an authoritative five-length win in the Grade II Tampa Bay Derby before returning to Keeneland in April to score a three-length triumph in the Grade I Blue Grass Stakes, his final Kentucky Derby prep race.
Bred by Coffee Pot Stable, Carpe Diem retires with four wins from six starts and earnings of $1,519,800.
Jockeys accused of fixing races
Three jockeys are accused in a race-fixing scheme that involved holding back a horse picked as a favorite and using an agent to place bets on the race at Evangeline Downs, state police in Louisiana said Thursday.
The investigation began after the state Racing Commission received a complaint about a June 19 race at the track in Opelousas in southwest Louisiana.
State police said the jockeys were each charged with "willful pulling of the reins and cheating and swindling."
Arrested were Joseph Patin Jr., 46, and Billy Patin, 51, both of Opelousas, and LeSean Conyers, 24, of Lafayette.
In addition, the Patins face charges involving different races. They are accused of possessing electronic shocking devices — allegedly during races on July 4 — that are sometimes illegally used to try to speed horses up.
The three have been released on bond from the St. Landry Parish jail. There was no answer at the phone number of an attorney listed as representing the Patins. Information on whether Conyers had an attorney was not available.
"Any deviations from honest and truly competitive horse racing cannot be condoned and the commission remains vigilant in its efforts to assure the highest standards possible," Louisiana Racing Commission Chairman Bob Wright said in the state police news release.
