Stevie Wonderboy, champion 2-year-old male and winner of the Bessemer Trust Breeders' Cup Juvenile (gr. I), suffered a condylar fracture of the right front leg during a workout Monday morning and has been knocked off the Triple Crown trail, trainer Doug O'Neill said.Owned by Merv Griffin, Stevie Wonderboy had finished second to Brother Derek in the San Rafael Stakes (gr. II) Jan. 14 in his 3-year-old debut.O'Neill said the injury was discovered after the son of Stephen Got Even worked six furlongs in 1:13 3/5."He worked fantastic," O'Neill said. "While he was cooling out, his groom commented that his ankle was filling up. We've been blessed with the fact that he's always had the coldest ankles you could ask on a horse. We checked it out, and could see the ankle filling up as we spoke. X-rays showed the beginning of a condylar fracture that will require one screw and 90 days off."We're all disappointed, and Merv was upset, but the important thing is that he'll be back. Timing-wise, it couldn't have come at a worse time, but these things happen in this sport; it's part of the game. It just shows you how hard it is to go through a grueling 2-year-old campaign and then come back on the Derby trail. It's a lot of wear and tear on a horse. We were all pinching ourselves that we had a horse like this. It was like, 'could this really be happening?' But we're so proud of him, and he's already given us some of the greatest moments we've ever had."Stevie Wonderboy has won four of six career starts, scoring in the Breeders' Cup Juvenile and Del Mar Futurity (gr. II).
