Orb to break from the inside post in the Preakness By Steve Ginsburg BALTIMORE (Reuters) - Kentucky Derby winner Orb, ridden by red-hot jockey Joel Rosario, drew the one post for Saturday's Preakness and has been installed as the prohibitive even-money favorite for the $1 million, nine-horse race. Rose Napravnik, looking to become the first female jockey to win the Preakness, will ride the second favorite, Mylute, a 5-1 morning line choice and will start from the five post. Illinois Derby champion Departing, a bay gelding who did not run in the Kentucky Derby two weeks ago, was listed on Wednesday as the third choice at 6-1 and will break from the four hole under Brian Hernandez. The mile-and-three-16ths Preakness, the middle jewel of U.S. thoroughbred racing's Triple Crown series, will be run over the dirt at Pimlico Race Course. If Orb can win the Preakness and remain healthy, the Shug McGaughey-trained colt will run in the Belmont Stakes on June 8 in New York with hopes of becoming the first Triple Crown winner since Affirmed in 1978. The Preakness field is the smallest since 2007 when nine horses also competed.
