Street Boss, a dual hemisphere stallion, is a son of Dubai World Cup winner Street Cry, who has rapidly attained the status as a sire of sires. He is the sire of more than 124 black-type winners, including Kentucky Derby winner Street Sense and three-time champion Zenyatta, one of the most popular horses in the history of American racing.
Street Boss has sired 30 black-type winners, eight graded, with four Gr. I winners in the U. S., including Kentucky Oaks winner Cathryn Sophia ($1,229,720), Arkansas Derby winner Danza ($866,428) and King's Bishop winner Capo Bastone ($731,756) and his progeny earnings have passed $35 million. His graded stakes-winners in Australia include such as Horse of the Year Street Rapper ($3,883,856) and The Quarterback (Gr. I, $1,192,426).
This is the second foal out of unraced Sepulveda Pass. Her first foal, the 3-year-old colt Four O'Five, has not started. She is a full sister to two stakes-winners and one stakes-placed runner. The filly Bel Air Sizzle was a six-time winner with earnings of $515,646, winning two stakes and finishing second in one Gr. I (Del Mar Oaks) and two Gr. II's, and third in two Gr. III's. Another filly, America's Friend, was a stakes-winner with earnings of $284,244, and the gelding Starspangled Heat was stakes-placed five times, including third in the Gr. II San Juan Capistrano Stakes at Santa Anita. A fourth sister, California Heat, earned $93,474 and has produced stakes-placed Beat the Heat.
