The first time the Breeders’ Cup was held at Del Mar, Gun Runner won the 2017 Classic – one of four Grade 1 wins in a Horse of the Year campaign. This year, as the Breeders’ Cup returned to Del Mar, Sierra Leone, a son of recently minted Hall of Famer Gun Runner, made his own case for championship honors with a victory in the Classic. Gun Runner, who stands at Three Chimneys Farm, appears poised to finish second to five-time reigning leading sire Into Mischief of Spendthrift Farm on North America’s general sires list by earnings. It would be the top placing thus far for the stallion, who has performed at an elite level ever since his emergence. Gun Runner set an earnings record for a North American freshman sire with his first crop in 2021, then finished sixth on the general earnings list in 2022, and third last year. As of Sunday, Into Mischief was the sire of 223 winners from 444 starters this year for progeny earnings of $32,084,358. Dubai World Cup winner Laurel River, who has earned more than $7.1 million this season, is the top earner from his 31 stakes winners this year. :: Bet the races with a $200 First Deposit Match + FREE All Access PPs!
