Champion Rachel Alexandra foals Bernardini filly

Stonestreet Farms’ Rachel Alexandra, the 2009 horse of the year, produced her second foal early Tuesday morning, giving birth to a Bernardini filly.

The filly was born at 2:30 a.m. and weighed 140 pounds — the farm’s largest foal so far this season, according to a post on Stonestreet’s Twitter account.

Rachel Alexandra’s first foal, born in January 2012, was a colt by¬† two-time horse of the year Curlin, who also was campaigned by Stonestreet. The colt, nicknamed “Taco,” has since been named Jess’s Dream after Stonestreet founder and wine mogul Jess Jackson, who died in April 2011.

Bred by Dolphus Morrison, Rachel Alexandra put together a historic unbeaten 3-year-old campaign in 2009, when she defeated males three times en route to winning horse of the year honors. The daughter of Medaglia d’Oro became the first filly in 85 years to win the Preakness Stakes, a feat she achieved two weeks after winning the Kentucky Oaks by a record-setting 20 1/4 lengths, and she captured the Grade I Haskell Invitational and toppled older males in the Grade I Woodward Stakes.

A five-time Grade I winner, Rachel Alexandra retired with 13 wins in 19 career starts and $3,506,730 for Stonestreet, which bought her from Morrison for $10 million after her Oaks triumph.
