Winchell Thoroughbreds' Tapit, who finished sixth in the Florida Derby (gr. I) in his 3-year-old debut, worked a mile in 1:47 2/5 at his home base of Tapeta Farm in North East, Md., in preparation for next Saturday's Wood Memorial (gr. I).Tapit has been plagued by physical maladies all year, missing 19 days of training with shin problems that kept him out of the Risen Star Stakes (gr. II), then coming out of the Florida Derby with a cough, mucous in his trachea, and an abscessed foot. This was his work since the race.According to racing manager David Fiske, Edgar Prado, who rode Tapit in the Florida Derby, is being sought to ride the son of Pulpit again on Saturday.In an odd statement regarding Saturday's work, it was pointed out that Tapit's work was "the second fastest workout of two at the distance."Neither trainer Michael Dickinson nor Fiske offered any further information about the work.Tapit was undefeated in two starts last year, winning the Laurel Futurity (gr. III) in brilliant fashion after a troubled trip.
