Stonestreet Farms’ Rachel Alexandra, the 2009 Horse of the Year, produced her second foal early Tuesday morning when she gave birth to a Bernardini filly.

The filly was welcomed into the world at 2:30 a.m. according to a post on Stonestreet’s Twitter account and weighed in at 140 pounds – the farm’s largest foal so far this season.

Rachel Alexandra’s first foal born last January 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 also 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 from 19 career starts and $3,506,730 for Stonestreet, which purchased her from Morrison for $10 million following her Oaks triumph.
