By the legendary stallion A. P. INDY, Flatter has proven his versatility, with winners on dirt and turf at distances of 7 furlongs to the classic 1 1/4-miles. In 2018, he was the number one sire of 2-year-old stakes winners. A full-brother to CONGRATS, Flatter is from the immediate family of SEA HERO (G1), ELATE (G1) and leading sire ROAR.
