male horses is the Strub Series. Due to the scheduling near the New Year period, the event was sometimes scheduled in late December as a three-year-old fillies event or in early January as a four-year-old fillies event, such as in 1982, 1985 and 1990 and thus the event would not be held in the calendar year - 1984 and 1986. American Triple Crown winner Secretariat's daughter Terlingua won this event in 1980. Later as a broodmare her offspring included a champion sire in Storm Cat (1999, 2000). In 1983 the American Graded Stakes Committee classified the event as Grade III. Also American Triple Crown winner Seattle Slew's daughter Savannah Slew won this event in December 1985. Although Savannah Slew retired after this event, Lady's Secret whom she defeated into second place in 1986 had an outstanding year culminating with a victory in the Grade I Breeders' Cup Distaff and winning the U.S. Champion Older Filly award and being voted as United States Horse of the Year. Prior to winning this event in 1988 Very Subtle had won the Grade I Breeders' Cup Sprint at Hollywood Park. Very Subtle dispatched her opposition by a record winning margin of nine lengths which continues to date to be the largest margin of victory. In 1991 the event was run in split divisions for the second time and since then has been scheduled only in December. In 1994 the event was upgraded to Grade II and to the highest classification of Grade I in 1997.
