Saratoga Springs, NY (My Sportsbook) - Leading thoroughbred racehorse Rachel Alexandra worked five-furlongs Monday morning on Saratoga's Oklahoma training track, even as her connections remain undecided on her next start.

"She looked beautiful coming down the lane," said trainer Steve Asmussen. "I saw her approaching the eighth pole and past the wire down to the turn. And the words (that) came out of Dominic's mouth: 'Never better.'"

Exercise rider Dominic Terry guided Rachel Alexandra through five-furlongs in 1:00.37. Her stablemate Kensei also worked five-furlongs Monday in 1:01.85.

"Kensei worked very well," said Terry, who was also aboard the colt. "I didn't think a horse could work better than the first set, then she went out. I don't have to ask her for anything; just hold on and let her do her thing. I couldn't ask for anything more."

Following the Monday morning work, Asmussen indicated that discussions on Rachel Alexandra's next start would begin "in earnest."

The filly defeated male three-year-olds for the second time this year in the Haskell Invitational at Monmouth Park on August 2. She has been nominated to the $600,000 Alabama for three-year-old fillies this Saturday, the $1 million Travers versus three-year-old colts and geldings on August 29, the $400,000 Personal Ensign against fillies and mares on August 30, and the $500,000 Woodward against older males on September 5. The $1 million Pennsylvania Derby on Labor Day at Philadelphia Park is also a possibility.

"There are no races eliminated," said Asmussen. "I will text [co-owner Jess Jackson] as to how the work went, he'll call me, and we'll discuss what we're going to do. We'll digest where we're at and try to do the best thing for Rachel."

Perfect in all seven 2009 starts, she has earned just under $2.3 million and has career winnings of nearly $2.5 million with 10 wins in 13 starts.

Rachel Alexandra remains atop the latest NTRA Thoroughbred Poll. The filly received 17 first-place votes and 188 points. Undefeated Zenyatta is second with two first-place votes and 167 points.
