Perennial leading sire Tapit led all North American stallions with 13 graded stakes winners in 2019. He is already off to a strong start toward defending his title in 2020, siring three stakes winners, two of those graded stakes winners at Fair Grounds, last Saturday.

Representatives for Ontario Racing’s Thoroughbred Improvement Program, which aims to increase the quality and value of Ontario-bred racehorses, say they are “extremely pleased” with the results of two incentive programs designed to bring mares and foals to the province.

Daily Racing Form's annual special edition takes an in-depth look at the past year's leading stallions standing in Kentucky, the epicenter of the North American bloodstock market, as well as surrounding states in the Midwest region.

Four-time Eclipse Award winner Beholder delivered her third foal this week, and in a vote of major confidence for one of its young stallions, owner Spendthrift Farm said she will stay home for this season’s mating.

Beholder delivered a War Front filly at Spendthrift in Lexington, Ky. The Henny Hughes mare, who was campaigned throughout her career by Spendthrift, will be bred back to Bolt d’Oro.

A multiple Grade 1-winning juvenile by Medaglia d’Oro, Bolt d’Oro is preparing for his second season at stud after garnering a solid book in his first season at Spendthrift.

Grade 1 winner Boisterous, who has been standing in California, is moving back East, where he spent the majority of his racing career. Boisterous is moving to Diamond B Farm in Mohrsville, Pa., for 2020.

He represents another prominent acquisition for Diamond B, which acquired Flashback from Hill 'n' Dale Farm in 2019. Flashback went on to be represented on the track by Breeders' Cup Juvenile Fillies winner and Eclipse Award finalist British Idiom.

Preakness Stakes winner and sire Shackleford has been exported to continue his stud career in Korea.

The relocation was first confirmed by trainer Dale Romans, speaking on At The Races with Steve Byk on SiriusXM Radio. Romans trained Shackleford throughout his career and conditions several of his top progeny. The stallion is no longer listed on Darby Dan Farm’s website, with the Kentucky farm’s roster now numbering nine stallions.

Al Shaab Stud, the largest Thoroughbred breeding operation in war-torn Libya, was raided on Saturday, with the farm's stallions and in-foal broodmares being stolen. Among the dozen horses stolen was former U.S. stallion Eavesdropper, a half-brother to Hall of Famer A.P. Indy, and the sire of popular millionaire Page McKenney.

Triple Crown winner Justify has been represented by his first reported foal, a filly born on Friday night.

Breeder Audley Farm reported the arrival of the filly, out of the winning Exchange Rate mare Foreign Affair, on Saturday, saying the foal was born the night prior. Audley Farm is located in Virginia, but Foreign Affair was boarded and foaled at Amaroo Farm in Kentucky.

In September, Phil Lebherz’s Premier Thoroughbreds was honored by the Thoroughbred Owners and Breeders Association as California’s outstanding breeder of 2018. The way Spiced Perfection continues to run, the operation could continue reaping awards.

Square Eddie has successfully developed from a young upstart in the California stallion ranks to a stalwart in his state of residence who makes an impact with graded stakes horses. Among stallions with California-sired progeny racing in 2019, he claimed the throne as the state’s leading general sire by progeny earnings.
