TOP-CLASS MARES FOR COOLMORE PAIR First-season Coolmore sires, Fusaichi Pegasus and Giant`s Causeway, have both attracted a top-class book of mares to be covered this year, the Thoroughbred Times website reports. Kentucky Derby winner Fusaichi Pegasus, stands at Coolmore`s American arm, Ashford Stud near Versailles, Kentucky, and Giant`s Causeway, at Coolmore Stud near Fethard, Co Tipperary. Giant`s Causeway, a four-year-old son of Storm Cat who earned the nickname 'the Iron Horse' for his exploits in Europe last season, has attracted 35 mares owned by American breeders. The group also includes 12 Group/Grade 1 winners, including Classic winners Sleepytime, Hula Angel, and Shahtoush. Other mares include Wannabe Grand, last year`s Arc de Triopmhe runner-up Volvoreta, Benediction, dam of two-times Australian Horse of the Year Might and Power, and La Papagena, dam of top miler and rising-star sire Grand Lodge. Fusaichi Pegasus, a four-year-old son of Mr Prospector who stands for US150,000, has sparkedan equal amount of interest. He has been booked to Solar Slew, the dam of two-time Horse of the Year and Breeders` Cup Classic winner Cigar, along with dams of champions and classic winners Thunder Gulch, Hansel, and Real Quiet. Both stallions are already completely booked, although Coolmore has not said exactly how many mares each stallion will cover.
