Scat Daddy, winner of the Florida Derby and Fountain of Youth Stakes in his last two starts, has been training with bar shoes on his front feet and had them on for his final workout Sunday at Keeneland. However, he will remove them for Saturday's Derby and race in conventional plates, trainer Todd Pletcher said.
Bar shoes are usually used to protect a tender part of a hoof. The shoes Scat Daddy was wearing "keep him from putting pressure on his inside quarters," Pletcher said.
"He won't run in them, but he has trained in them," Pletcher said. "It's not something new. He's had bar shoes, or similar shoes, since July. I'd say that in the last year, for 10 months he's trained in bar shoes. He might not need them any more, but I'm not going to take a chance now."
