Nobiz Like Shobiz showed improved focus with the addition of blinkers to capture the Wood Memorial on Saturday at Aqueduct. Cowtown Cat bested the Illinois Derby field for trainer Todd Pletcher. Merv Griffin's favored Cobalt Blue likely raced himself out of the Kentucky Derby with a bad showing in Chicago. Tiago, a half-brother of 2005 Kentucky Derby shocker Giacomo, played the spoiler's role to take the Santa Anita Derby and pay $60.60. Tiago is trained by John Shirreffs and was ridden by Mike Smith. Now he will head to Louisville. The $750,000 Blue Grass at Keeneland and the $1 million Arkansas Derby at Oaklawn Park top this Saturday's final preps for the 133d Run for the Roses.
