Reigning Horse of the Year Rachel Alexandra fired her third straight bullet at Churchill Downs on Monday morning, firing off six furlongs in 1:11.40.

With regular exercise rider Dom Terry aboard, the Medaglia d'Oro filly reeled off splits of :12.56, :24.28, :36.16, :47.67 and :59.29. She galloped out seven furlongs in 1:24.41 and the mile in 1:37.76.

Her work was the fastest of seven at the day, outworking stakes-winning stablemates Friesan Fire (1:13.20) and Hot Dixie Chick (1:13.60).

Last Monday, Rachel Alexandra worked six furlongs in 1:12, best of seven, and on April 5, she covered five furlongs in 1:00.20, best of 16.

No race has been named for the filly's next start. However, she is nominated to the Grade II La Troienne Stakes on the Kentucky Oaks undercard next week. There, Rachel Alexandra could meet Zardana, who defeated her last out in the New Orleans Ladies, and Careless Jewel, winner of the Alabama last summer.
