In a sport in which margins of victory can be measured in fractions of a second, the plans for top stallion prospects can change in the blink of an eye.

Essential Quality
Tapit – Delightful Quality, by Elusive Quality
Bred in Kentucky by Godolphin

Tapit, among the most successful sires in modern classic history, has three individuals in the first Derby Watch Top 20 list. That trio is led by Godolphin’s homebred Breeders’ Cup Juvenile winner and Eclipse Award champion Essential Quality, already a multiple Grade 1 winner around two turns.

Multiple Grade 1 winners Blue Prize and Elate each produced her first foal, both fillies, early Tuesday morning in Kentucky.

Blue Prize won the 2019 Breeders’ Cup Distaff over Midnight Bisou, and two days later sold for a sale-topping $5 million to Larry Best’s OXO Equine at the Fasig-Tipton November sale. Best bred her to leading sire Into Mischief, and the Pure Prize mare delivered her filly at Taylor Made in Kentucky, where she is boarded. Best intends to breed her back to his Grade 1 winner Instilled Regard, who enters stud this season at Taylor Made.

Our annual Eastern Stallions special edition, presented by the New York Thoroughbred Breeding and Development Fund, takes a closer look at the leading sires in that state of New York, as well as the Mid-Atlantic region of Maryland and Pennsylvania, the Florida market, and other states.

Uncle Mo was expected to be a fine sire of juveniles. After all, he had been an Eclipse Award champion 2-year-old himself. However, no one could have predicted the scope of his early success, as he broke the mold with a record-setting freshman season.

American Pharoah knocked it out of the park as a racehorse, first becoming a long-awaited hero for the sport when connecting for the 2015 Triple Crown, and then again dazzling the crowd with a victory in the Breeders’ Cup Classic. Thoroughbred marketing dubbed the combination of victories the sport’s first “Grand Slam.”

“The Giving Tree,” a 1964 children’s book written and illustrated by Shel Silverstein, follows the lives of an apple tree and a boy as he grows. The namesake tree gives to the boy throughout his life, even as his needs change – from a place to play as a child, to her branches to build a house as a young man, to a place to rest when he is elderly.

Like the apple tree, Into Mischief can do it all.

Champion Zenyatta lost the foal she was carrying earlier this month, her connections reported Tuesday morning, the latest incident in a streak of bad luck for the Hall of Fame racemare as a broodmare. 

Four Wheel Drive, a Breeders' Cup winner as a juvenile, has been sold to begin a stallion career in Japan. The 4-year-old by American Pharoah will become the first son of his Triple Crown-winning sire to stand at stud.

Caddo River threw his name into the ring for Kentucky Derby consideration with a 10 1/4-length score in Friday’s Smarty Jones Stakes, the first race in Oaklawn Park’s series of Kentucky Derby prep races. In the process, the Shortleaf Stable homebred continued nearly a century of success for his tail-female line.

Caddo River’s dam, Pangburn, by Congrats, became the ninth consecutive member of her direct female line to produce at least one stakes winner. The young broodmare is one of three stakes winners produced by her dam, the Yes It’s True mare It’s True Love.
