HOT SPRINGS, Ark. (AP)—Oaklawn Park is throwing $5 million at star females Rachel Alexandra and Zenyatta to meet for the first time at the Apple Blossom in April.

The racetrack in Hot Springs announced Thursday that the owners of both champion horses are receptive to the idea. No firm commitments have been made.

“This is an event of a lifetime,” said Pat Pope, Oaklawn’s racing secretary. “We’re going to do everything to bring them to the state of Arkansas.”

Rachel Alexandra won 2009 Horse of the Year honors over Zenyatta. The 4-year-old Rachel and 6-year-old Zenyatta have never met on the track to settle who is the best.

Oaklawn said the $5 million purse will be offered only if both horses enter. If not, the purse will revert to $500,000 as initially planned.

No matter who is in the field, the Apple Blossom distance has been increased from 1 1/16 miles to 1 1/8 miles.

Rachel Alexandra is training at the Fair Grounds in New Orleans. Her first race this year is undetermined. She went 8-0 last year, including the Preakness and two other wins against male horses.

Zenyatta had been off to retirement after capping a 14-0 career with a win in the Breeders’ Cup Classic. But now she’s back for another year and might run in the Santa Margarita Handicap at Santa Anita on March 13.

Zenyatta, who won the 2008 Apple Blossom, is owned by Jerry and Ann Moss, and trained by John Shirreffs. Rachel, who won twice at Oaklawn last year, is owned by Jess Jackson and Harold McCormick and trained by the nation’s top trainer Steve Asmussen.

“My family and I would love to see her run at Oaklawn Park. If she is in top form and it fits in our schedule, we will be there,” Jackson said. “As you have heard me say many times before, a number of factors must be considered when deciding where to race a horse—the number one factor being the condition of the horse. Rachel will tell us when she is ready to start her 2010 campaign and we humans must agree she is in top form.”
