Evidence: 25: 17-2-2 
Undeafted 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. Primonetta continued her winning ways at age four, setting a new stakes record in capturing the Spinster Stakes and equaled the Monmouth Park track record in winning the Regret Handicap. Primonetta closed out her racing career with a victory in the November 4, 1962 running of the Falls City Handicap.
