Trainer Robert Frankel made it perfectly clear the morning after the Kentucky Derby what his plans are for Medaglia d'Oro, who finished fourth with a troubled trip, eight lengths behind the victorious War Emblem. "I'm going to win the Preakness with him," Frankel said. The son of El Prado is scheduled to ship Monday to Frankel's barn at Belmont Park, where he will train up to the Triple Crown's middle jewel. The Hall of Fame conditioner said he likely will wait until Preakness eve to van the horse to Pimlico."He ran a very good race," Frankel said of the colt purchased privately by Edmund Gann in February, "especially when you consider all the trouble he had. Laffit (jockey Laffit Pincay Jr.) said he was standing great but had his head turned at the start, so he broke slowly. Down the backstretch he had to steady, steady, steady because he was behind so many horses. It's a shame it happened in the Kentucky Derby."Despite the problems in the race, Frankel remained upbeat about his colt. "I've got no complaints. The track was fair. My horse just had bad luck. You get depressed when your horse runs a bad race, but he ran good."
