Leading sprinter Majesticperfection has retired after undergoing surgery for his fractured right front cannon bone, owner Satish Sanan announced Tuesday. The announcement was widely expected. The 4-year-old Majesticperfection injured himself Sunday morning during a workout and had surgery the same day at Saratoga Equine Clinic. “While we are guardedly optimistic about the results of the successful surgeryand have a prognosis of a successful recovery, Majesticperfection will not return to racing,” Sanan said. There are no stud plans as yet. Sanan bought Majesticperfection for $370,000 at the 2008 Ocala Breeders’ Sales Company’s April juvenile auction, where the colt topped the sale. Trained by Steve Asmussen, he developed into a Grade 1 winner this year when he won the Alfred G. Vanderbilt Handicap on Aug. 8 by nearly three lengths. In his previous start, he won the Iowa Sprint Handicap in track-record time, covering six furlongs in 1:07.24. He retires with 5 wins and a third in 6 career starts. Bred in Kentucky by Ronald McPeek and Shane Floyd, Majesticperfection is a son of Harlan’s Holiday out of the Wavering Monarch mare Act So Noble. He is her first stakes winner.
