California stallion Lucky Pulpit, sire of two-time Horse of the Year California Chrome, has died of a heart attack at age 16.
The Pulpit stallion was covering his first mare of the season at Harris Farms in Coalinga, Calif., which he had called home for the past decade, when he collapsed. Farm manager David McGlothlin and stallion manager Raul Rosa were there when it happened, according to a statement from Harris Farms.
