Monomoy Girl, one of the top racemares of the past decade, will be bred to elite sire Gun Runner for the 2026 breeding season.
Owner Spendthrift Farm announced the plan Monday via its social media accounts.
The mating would produce Monomoy Girl’s third foal, after producing a pair by Spendthrift’s cornerstone sire Into Mischief. The first, a colt named Provenance, is a 2-year-old of 2025, finished third on debut in a Del Mar maiden special weight on Aug. 23 for Spendthrift Farm and trainer Bob Baffert. He was followed by a filly, who is now a yearling.
Monomoy Girl, a 10-year-old Tapizar mare, won 14 of 17 starts and earned $4,776,818. She earned the Eclipse Award as champion 3-year-old female in 2018, and she picked up another Eclipse as champion older female in 2020. Her seven Grade 1 wins include two editions of the Breeders’ Cup Distaff, and the Kentucky Oaks.
Spendthrift purchased Monomoy Girl for $9.5 million at the 2020 Fasig-Tipton November Sale.
Gun Runner stands at Three Chimneys Farm, where he has established himself as one of North America’s top sires on the racetrack and in the breeding shed.
The 12-year-old son of Candy Ride currently ranks third on the North American general sire list by earnings, with $13,868,131, with runners of note in 2025 including Grade 1 winners Brant, Locked, and Sierra Leone.
Gun Runner was the leading sire of this year’s Keeneland September Yearling Sale by average sale price, at $877,125. He had 12 horses change hands for $1 million or more, led by the $3.3-million sale-topper.
During his own on-track career, Gun Runner 12 of 19 starts and earned $15,988,500, securing Horse of the Year honors in 2017 and later a spot in the Hall of Fame.
