Reigning Horse of the Year Rachel Alexandra, in her final work in Kentucky before shipping to New York, went an easy five furlongs in 1:03 Monday morning at Churchill Downs.

The work, the 4-year-old filly's second since getting her first win of 2010 in the Grade II Fleur de Lis, took place over a sloppy track that had been sealed.

Rachel Alexandra is set to ship to trainer Steve Asmussen's barn at the Oklahoma training track on Wednesday. The filly was based there from late June to late September in 2009, shipping out to win the Haskell and also claiming the historic Woodward Stakes, the first female ever to do so.

Last year's Kentucky Derby winner Mine That Bird fired the fastest of the 26 five furlong works of the morning, going in :59.80.

The gelding will ship to Saratoga on July 12, with his goal being the Whitney Handicap on August 7. The race is shaping up as a showdown between the East's top two older males, Quality Road and Blame.

Also working Monday at Churchill was Rachel Alexandra's stablemate Kensei, who won the Jim Dandy last summer. He went the five furlongs in 1:02. Macho Again, the 2008 Jim Dandy winner who finished third in the Whitney and second to Rachel in the Woodward last summer, went four furlongs in :51.60.
