MASTER Imp once again reigns as the top Irish-based stallion in the Rolex World Breeding Federation for Sport Horses 2017 sire rankings released this week. Featured each year in their top-10 eventing sire rankings over the past decade, Slyguff Stud’s home-bred topped the 2014 leaderboard and ranked third this year. Best of his progeny was the William Micklem-bred High Kingdom that placed third at the Rolex Kentucky CCI4* last April.
