Liam's Map: Burnham Square highlights his sire's versatility
Liam's Map, the 2015 Breeders' Cup Dirt Mile winner, has established himself as a successful stallion with multiple Grade 1 winners, including Colonel Liam, Deterministic and Burnham Square, winner of the Blue Grass on his way to the Kentucky Derby. Standing at Lane's End Farm in Kentucky, his stud fee was $40,000 for the 2025 breeding season.
Burnham Square tried turf for the first time in the Nashville Derby (G3) at Kentucky Downs, where he missed the win by a head to the Euro shipper Wimbledon Hawkeye. This performance so impressed his trainer Ian Wilkes that he told Blood-Horse the 3-year-old colt is taking the rest of the year off and will return as a turf horse next year. And that tracks for Liam's Map as a sire, as his top earners show how versatile this son of Unbridled's Song really is.
During his racing career, Liam's Map compiled an impressive record with victories in the Woodward Stakes (G1) and Harlan's Holiday before his career-defining triumph in the 2015 Breeders' Cup Dirt Mile. As of Sept. 2, his progeny had accumulated over $44 million in earnings from 5,113 starts, with 859 wins and 28 graded-stakes victories.
