Candy DeBartolo’s Life At Ten, the recent winner of the Grade II Delaware Handicap, will take aim the reigning Horse of the Year Rachel Alexandra in the mile and a quarter $300,000 Grade I Personal Ensign at Saratoga this Sunday. Life At Ten will be putting her six race win streak on the line when she meets three other rivals.

In her last outing, the 5-year-old daughter of Malibu Moon scored an easy 3-length front running victory in the mile and a quarter $750,000 Delaware Handicap on July 17. Previously, the Kentucky-bred trained by Todd Pletcher notched a 2 ¾-length in the mile and a sixteenth $250,000 Grade I Ogden Phipps Handicap at Belmont Park on June 12. She will be bringing a career record of seven wins, five seconds and a third from 14 starts into the Personal Ensign.

“The Personal Ensign is a natural progression as it made sense to keep her at a mile and a quarter,” said Todd Pletcher, who trains the 5-year-old daughter of Malibu Moon for Candy DeBartolo. “It just so happens that Rachel Alexandra is going to this race, but we are sticking with our plan.”

Life At Ten enters the Personal Ensign on a six-race winning streak which includes victories in the Grade 3 Sixty Sails Handicap at Hawthorne in April and the Grade 1 Ogden Phipps Handicap in June at Belmont.

“She has gotten better and better as she has gotten older,” said Pletcher. “It was something we thought would happen, although it took longer than we had hoped.”

Life At Ten has raced on or right off the lead in her four most recent starts, but Pletcher believes that doesn’t necessarily mean his filly will be winging out front with Rachel Alexandra.

“Our filly has tactical speed; she can place herself where she needs to be,” said Pletcher. “I think she’ll be forwardly placed, but we’ll play it by ear.”

Since winning the Eclipse Award for Horse of the Year after posting eight straight victories in 2009, Rachel Alexandra has started to put it all together this year. The 4-year-old daughter of Medaglia d’Oro opened her 2010 campaign by being upset by Zardana in the mile and a sixteenth $200,000 New Orlean Ladies at the Fair Grounds on March 13. The Kentucky-bred trained by Steven Asmussen followed by running second in the mile and a sixteenth $400,000 Grade II La Troiene at Churchill Downs on April 30. On June 12, she posted her first victory of the year with a 10 ½-length triumph in the mile and an eighth $200,000 Fleur de Lis at Churchill Downs. In her most recent outing, she posted a 3-length score in the mile and an eighth $412,000 Lady Secret Stakes at Monmouth Park on July 24. She has a career record of 13 wins and four seconds from 18 starts with earnings of $3,446,730.

“The filly is a year older, and she’s carrying a little more weight, a little heavier than she was then,” said Asmussen. “There are no comparisons to the situation when she moved into the barn last year. It’s impossible to duplicate, moving into the barn four days off of a big race and 10 days before a classic. You can’t recreate that sort of tension or pressure on her, so it’s obviously a lot more relaxed this year.”

Rachel Alexandra has been stabled at Saratoga since June 30, and Asmussen is happy with the way she has progressed following the Lady’s Secret.

“We’re trying to keep her in a rhythm and keep her happy, and we feel that’s where she’s at,” said Asmussen.

Calvin Borel, who has piloted Rachel Alexandra in her past 13 starts, will ride the 4-year-old filly once again on Sunday. The 2-5 morning-line favorite, she drew post position 2.
