Background Check: Acorn

In this continuing series, we examine the past winners of significant filly/mare races by the lasting influence they've had on the breed. Up today is Belmont Park's GI Acorn S., the first leg in New York's prestigious summer trio of Grade I events for 3-year-old fillies.

Long a coveted prize, the Acorn has been designated a Grade I from the very beginning when the grading system became official in 1973. A disproportionate amount of its winners are in the Hall of Fame, ranging from Top Flight to Twilight Tear to Cicada to Ruffian, and so many more. The quality of the Acorn winners set the tone for their broodmare careers as well. Not surprisingly, the Acorn boasts a ridiculous number of high-class future broodmares among its winners, including a glorious five-year streak in the 1950s that saw five consecutive winners eventually cultivate champions among their descendants.

Following are highlights of some of the most important Acorn winners by what impact they've had on the sport through their sons and daughters.
