According to MyRacehorse, Monomoy Girl exited a routine gallop Tuesday at Churchill Downs with mild lameness. Diagnostics discovered a non-displayed fracture of the sesamoid bone in her right foreleg.

“Obviously, we’re very disappointed,” Cox was quoted as saying in the report to shareholders. “She’s walking sound today and it’s not anything that will require surgery. It’s just unfortunate that it will end her racing career.”

Spendthrift Farm acquired Monomoy Girl last year at the Fasig-Tipton Kentucky Fall Selected Mixed Sale, a day after she won the Breeders’ Cup Distaff (G1) for the second time in 3 years.

The daughter of Tapizar made history when Spendthrift Farm bought her last November for $9.5 million, as it tied her for second all-time among racing or broodmare prospects sold at public auction in North America. through a lease agreement with Spendthrift Farm MyRacehorse offered 10,200 total shares at $46 per share for Monomoy Girl’s 2021 racing campaign.

In her 2 starts in 2021, both at Oaklawn Park, Monomoy Girl won the Bayakoa Stakes (G3) and finished second in the Apple Blossom Handicap (G1). According to, Monomoy Girl distributed $11.22 per share from those combined efforts.

“Certainly, we are disappointed, especially for all of our partners,” said Ned Toffey, General Manager at Spendthrift Farm, where she will become a broodmare starting in 2022. “While we were hopeful to get her back to the races this year, we won’t lose focus on what is most important and that is a healthy Monomoy Girl. She’s an all-time great and we look forward to the next chapter of her career and giving her a great life on the farm at Spendthrift.”
