Her name is Italian for first little one since she was Swaps' first foal. Primonetta was a chestnut.
Racing career
As a three-year-old in 1961 Primonetta was one of the top fillies in American racing. Undefeated at two, her win in the April 12th Prioress Stakes was her sixth straight career win without a defeat. Among her other victories that year, she won the Delaware Oaks on July 16 for her ninth win without a loss then suffered her first loss on Jul 23, 1961 in the Monmouth Oaks. She rebounded to beat the great Bowl of Flowers by more than five lengths in her winning effort in the Alabama Stakes.[2]
Primonetta died of a heart attack on January 16, 1993, at Darby Dan Farm, less than a month before her thirty-fifth birthday. She is recognized as one of the longest-lived thoroughbred racehorses ever, and is the third longest-lived filly known to horse racing after Stay Out Front (February 28, 1966 – December 15, 2001), who lived to 35 years and 9+1⁄2 months and Heartake (May 22, 1973 – April 8, 2009), who lived to 35 years and 10+1⁄2 months.
