Nehro, Zayat Stables' runner-up in the 2011 Kentucky Derby, died of colic May 4 while en route to a clinic.
In training with Steve Asmussen at Churchill Downs, the 5-year-old horse fell ill the morning of May 4. According to the trainer, his condition "spiraled badly."
"I can't put into words how much respect I have for Nehro," Asmussen said. " He was loved by everyone around the barn. What a cool horse. Quality animal. Just a horrible, horrible deal."
"I am deeply saddened," owner Ahmed Zayat said. "Nehro was my favorite horse, whom I had a deep bond with. Everyone who came into contact with this horse loved him. He cannot be replaced, and I'm devastated."
Zayat purchased Nehro for $170,000 at the Keeneland September yearling sale. The bay colt became one of the top 3-year-olds on the 2011 Kentucky Derby trail.
Along with his second by a three-quarters of a length to Animal Kingdom in the Kentucky Derby, Nehro finished a close runner-up in the grade I Arkansas Derby, Grade 2 Louisiana Derby, and Grade 3 Pimlico Special Stakes.
