Silver Medallion wins the El Camino Real Derby at Golden Gate Fields.
A majority interest in Silver Medallion, the El Camino Real Derby winner, was sold Thursday to Blackrock Racing Partners, a partnership headed by oil entrepreneur Steve Marshall, according to both Marshall and Michael Ryan, who previously owned 100 percent of the colt.
“I’ve sold a little over 50 percent,” Ryan, a bloodstock agent based in Kentucky, said from Ocala, Fla., where he is attending a 2-year-old sale. “The horse will remain with Steve Asmussen.”
