ARCADIA, Calif. -- Stevie Wonderboy, the champion 2-year-old colt of 2005, will miss the May 6 Kentucky Derby after suffering an injury to his right front ankle in a workout at Hollywood Park on Monday, owner Merv Griffin and trainer Doug O'Neill said.
The preliminary diagnosis is a hairline condylar fracture which will require surgery to insert a stabilizing screw, followed by 90 days' rest, O'Neill said.
O'Neill said that further tests would be taken before surgery is conducted. O'Neill said he noticed that a filling had developed in the colt's ankle following a six-furlong workout Monday in 1:13.60. X-rays were quickly taken and they revealed a more serious injury.
Said Griffin: "He's out of the Derby. It's the saddest thing in my life."
Stevie Wonderboy has won 4 of 6 starts. At 2, he won 3 of 5 starts, ending his campaign with three consecutive wins - a maiden race at Del Mar in August, the Grade 2 Del Mar Futurity in September, and the Breeders' Cup Juvenile at Belmont Park in October.
In his only start this year, Stevie Wonderboy finished second to Brother Derek in the Grade 2 San Rafael Stakes at Santa Anita on Jan. 14. He was being prepared for a start in the $200,000 Santa Catalina Stakes on March 4 when the injury was detected.
The defection of Stevie Wonderboy from the Kentucky Derby continues a dubious streak: A 2-year-old champion has not won the Kentucky Derby since Spectacular Bid in 1979.
