Hill ‘n’ Dale Farm resident Curlin continues to build a strong reputation as a sire of top sale horses and successful runners. His newly turned yearlings already have topped mixed sales at the Ocala Breeders’ Sales Co. and Fasig-Tipton’s Midlantic branch in 2016. That upward trajectory continued Wednesday night at the Fasig-Tipton Florida sale, where Sheikh Mohammed bin Khalifa Al Maktoum purchased a colt by the two-time Horse of the Year for $1 million, making him the second Curlin offspring to command seven figures at auction. The first was Leslie’s Harmony, a half-sister to champion Beholder and Grade 1 winner and popular stallion Into Mischief who sold to Bridlewood Farm for $1.1 million at the 2014 Keeneland September yearling sale. Wavertree Stables consigned the colt, out of the A.P. Indy mare On a Roll, as agent Wednesday. Curlin, a son of Smart Strike, saw his stud fee rise from $35,000 to $100,000 upon his move from Lane’s End Farm to Hill ‘n’ Dale for the 2016 breeding season.
