Toyota Blue Grass winner Dullahan, most recently third in the Kentucky Derby, continued his preparations for the Belmont Stakes with a five-furlong breeze in 1:00 1/5 on the fast main track at Churchill Downs May 19 for trainer Dale Romans.
Working on his own after the renovation break under Faustino Aguilar, Dullahan recorded fractions of :12, :23 4/5, :35 4/5, :47 4/5. He galloped out six furlongs in 1:13 4/5 and seven furlongs in 1:29 4/5.
His five-furlong time, his first published work since the Derby, was the second fastest of 26 at the distance. This year's Belmont Stakes is June 9.
Assistant trainer Baldemar Bahena oversaw the workout for Romans, who is in Baltimore to saddle Cozzetti for the 137th Preakness.
"He came out of the Derby very well and today's work was good," Bahena said. "He will work again here next Saturday and then we will ship him to Belmont. He'll have his final workout for the race up there."
Donegal Racing owns the chestnut son of Even the Score and the Smart Strike mare Mining My Own. Dullahan is a half-brother to 2009 Kentucky Derby winner Mine That Bird, who ran second to eventual Horse of the Year Rachel Alexandra in the Preakness and third in the Belmont behind Summer Bird and Dunkirk .
Dullahan, who won the Dixiana Breeders' Futurity at Keeneland last October in addition to the Blue Grass, owns a career record of 2-2-3 in nine starts with earnings of $1,072,091.
