Tuesdee Testa

Dark Mirage At age 25, Testa was the regular exercise rider for Dark Mirage (1965), a small, dark brown thoroughbred filly referred to as "pint-sized" and affectionately known as an "equine prankster" which earned her the nickname "Tiny Tigress". Testa also fed, walked and groomed the filly, and became quite attached to her. As a three-year-old, Dark Mirage began the season with a defeat at Aqueduct, finishing fourth behind the winning horse ridden by Ron Turcotte; however, that defeat led to a remarkable turn-around and nine consecutive wins, including eight stakes races.

Dark Mirage was the 1968 Champion Three-year-old Filly. She set track records, winning the Acorn Stakes by 6 lengths, Mother Goose by 10 lengths and Coaching Club American Oaks by 12 lengths, which comprised the 3 legs of the American Triple Tiara of Thoroughbred Racing, formerly known as the Filly Triple Crown or New York Filly Triple Tiara that was originally hosted at Belmont Park (1957-2002 and 2007–2009).

As a four-year-old, Dark Mirage ran the Santa Maria Handicap marking her 10th win. Her next race was the 1969 Santa Margarita Invitational Handicap. Bion Abbott of the Los Angeles Times described trainer Everett King's position going into that race as leading with "a couple of queens in his hand", referring to Dark Mirage, and Testa, who he described as "5-foot 2, eyes of blue, 35-23-36, a trim 112 pounds and the first feminine jockey in Santa Anita history." She eventually settled in a rural area near Davie, Florida, where she was one of a group of 54 volunteers riding on horseback with a Crime Watch Mounted Patrol in 1986. Testa then worked as a trainer at Remington Park in Oklahoma City, Oklahoma, after it opened in 1988.
