A Spendthrift-Bred son of Into Mischief was the highest priced yearling by his sire to sell during Session 1 of Book 1 at the 2026 September Keeneland Sale striking at $1,250,000 to Mike Ryan, agent.

The colt is out of the Gun Runner mare Sixtythreecaliber, herself a G3 winner of the 2022 Comely Stakes at Aqueduct. She was owned in partnership with Spendthrift Farm and MyRacehorse and took her owners to Grade 1 heights by running in multiple Grade 1 races at Saratoga, Keeneland, and Churchill Downs. This is her first foal and she produced a full sister in 2026.
