Rachel Alexandra (Medaglia d’Oro) continued her domination of the three-year-old filly ranks when she spreadeagled the G1 Kentucky Oaks (G1) field by 20 lengths on Friday.

The margin of victory is believed to be an Oaks record.  The largest previous victory margin was 10 lengths, a feat last achieved by Lite Light in 1991.

“It was just unbelievable,” said trainer Hal Wiggins, a training veteran of 40 years who notched his first win in a Group 1.  “She just took off a just finished tremendous.

“Te owner still owns the dam, so that’s very important.  And I’ve trained for the man for 30 years.  It’s a good feeling to me for him to be able to experience this.”

Co-owner and breeder Dolphus Morrison did not mince words when asked if Rachel Alexandra would take on the colts in the Preakness Stakes.

“No sir, the Triple Crown races are to showcase the future stallions of our industry and fillies should run with fillies and stallions with stallions,” he said.

Rachel Alexandra broke her maiden in her second try at Churchill Downs and earned her first black-type victory in the Golden Rod Stakes (G2).

She won the LR Martha Washington Stakes Oaklawn Park when resuming this year and added the Fair Grounds Oaks (G2) in New Orleans before tuning up for the Kentucky Oaks with a yet another easy score in the Fantasy Stakes (G2) at Oaklawn.

Bred in Kentucky, Rachel Alexandra is the first foal out of stakes winner Lotta Kim (Roar), who finished second in the 2003 edition of the Golden Rod and has a juvenile colt named Empire Ruler (Empire Maker).
