Breaking sharply from her far outside post position and never giving up the lead, Rachel Alexandra became the first filly in 85 years and the first horse ever from post position #13 to win the Preakness Stakes.

“She’s every jock’s dream,” said Calvin Borel, who gave up the mount on Kentucky Derby winner Mine That Bird to ride Rachel Alexandra for owner Jess Jackson and trainer Steve Asmussen, who purchased the Medaglia d’Ore filly 10 days ago for a reputed $10 million.

Mine That Bird came from last to finish second by one length under Mike Smith.

“He’s a great little horse,” said Smith of the 15.1-hand colt, who proved in the Preakness that his 50 to 1 shot Kentucky Derby win was not a fluke. “But that mare ran huge.”

“I knew he would be coming,” said Borel of Mine That Bird. “I saw him coming, but when he ran up, she picked it up.

“She struggled a little bit with the ground today,” he added. “She never really got into the rhythm that she usually has. She loves hard tracks and this track was a little deep and really dry.

Rachel Alexandra is also the first Kentucky Oaks winner to win the Preakness.

It was the first Preakness victory for Borel, who finished second on Derby winner Street Sense in the 2007 Preakness, and the second Preakness win for Asmussen and Jackson, who accomplished the feat with Curlin in 2007. Ironically, Curlin was defeated in the Belmont by Rags to Riches, the first filly to win the race in more than 100 years.

“I will seriously consider running her in the Belmont, if the conditions are right,” said Jackson of Rachel Alexandra. “We’ve definitely seen she can run against colts.”
