Nehro, the three-year-old colt who was eclipsed by Animal Kingdom in the final stretch of the Kentucky Derby, will not run in this Saturday's Preakness Stakes, the second leg of horse racing's Triple Crown. The second-place finisher will rest and prepare for the longer Belmont Stakes on June 11 at Belmont Park, in New York's Nassau County.

Owner Ahmed Zayat told the Daily Racing Form that the colt had run three hard races in six weeks, and he says he thought four stakes races in eight weeks would be too much for the young horse.

With Nehro out, the winner, third-place horse, and fourth place finisher of the Kentucky Derby--Animal Kingdom, Mucho Macho Man, and Shackleford--will dominate the odds at Baltimore's Pimlico Race Course on Saturday.

Derby favorite Dialed In will draw some attention as well. His breeding and his performance this spring--coming from behind late in all his wins--suggests Dialed In likes to close rather than sprint. The Preakness Stakes is the shortest of the three Triple Crown races at 1 3/16 mile.

However, last year's winner, Lookin at Lucky, was not considered a sprinter, either.

Dialed In made his move to challenge the field in the 1 1/4-mile Kentucky Derby a little late, and finished eighth. Jockey Julien Leparoux will need to push him earlier in this shorter race.
