The Preakness field has now doubled in size from last week with the confirmations of New York Hero and Foufa's Warrior as definite starters for the second leg of the Triple Crown.New York Hero, winner of the Lane's End Stakes at Turfway Park, has been beaten in the Wood Memorial and Withers Stakes since that victory, but trainer Jennifer Pederson feels if the son Partner's Hero is allowed to rate, he will be competitive with the Preakness horses. In the Lane's End, New York Hero defeated subsequent Arkansas Derby runner-up Eugene's Third Son and subsequent Derby Trial runner-up Champali. Pederson has not secured a rider yet, but was in contact with Javier Castellano's agent.Foufa's Warrior, was announced as a definite starter this morning by trainer Lawrence Murray. The gelded son of Jade Hunter was a well-beaten third in the Illinois Derby, then finished a fast-closing third to Preakness hopeful Senor Swinger in the Crown Royal American Turf at Churchill Downs. Harry Vega will ride.The dozen horses now pointing for the Preakness are Funny Cide, Peace Rules, Senor Swinger, Scrimshaw, Ten Cents a Shine, Kissin Saint, Midway Road, Alysweep, Champali, Cherokee's Boy, New York Hero, and Foufa's Warrior.
