Multiple grade I winner Royal Anthem has gotten off to a promising start as a stallion. The first-year sire has had 29 mares pronounced in foal, 28 of those on only one cover. The son of Theatrical (Ire.) is booked full.Royal Anthem earned just under $1.9 million on the racetrack for The Thoroughbred Corp., who is supporting him strongly in the breeding shed. Among the mares in his first book is grade I winner Oath."We're obviously quite pleased with the high fertility of Royal Anthem," said Rick Trontz, whose Hopewell Farm near Midway, Ky., stands the stallion. "He's an easy stallion to manage and a quick and efficient breeder. If his babies have any of his class, they'll be something special."Theatrical has sired 55 stakes winners. Royal Anthem's grandsire, Nureyev, and his great-grandsire, Northern Dancer, each sired more than 100 added-money winners. Out of 1998 Broodmare of the Year In Neon, Royal Anthem is a half-brother to $2-million- earner Sharp Cat. Royal Anthem stands at Hopewell for a 2001 fee of $10,000 live foal. He ran second in the 1999 Breeders' Cup Turf (gr. I) behind Daylami.
