The official wooing of Rachel Alexandra ended a few hours after it began.

Despite the lure of an extra $1 million by Breeders' Cup Ltd., Rachel Alexandra's co-owner said his 3-year-old filly won't run in the Breeders' Cup Classic at Santa Anita Park on Nov. 7.

Jess Jackson said late Friday he was humbled by the interest his 3-year-old filly has generated, but "Rachel already has completed a brilliant long campaign."

Earlier Friday, in an effort to lure Rachel Alexandra to the Breeders' Cup to run against undefeated Zenyatta, the Breeders' Cup said it would add $1 million to the winner's share of the $5 million Classic if both horses ran in America's richest race.

Jackson put an end to that possibility quickly, reiterating that he dislikes Santa Anita's synthetic surface. "These false tracks create potential for injury, a risk I am not willing to take with Rachel," he said in a statement to The Associated Press.

The official wooing of Rachel Alexandra has begun.

The Breeders' Cup said Friday it will add $1 million to the winner's share of the $5 million Breeders' Cup Classic at Santa Anita on Nov. 7 if both Rachel Alexandra and Zenyatta start in America's richest race.

However, money might not be enough to match two of the world's top thoroughbreds for the first time at racing's championship weekend.

Jess Jackson, who co-owns Rachel Alexandra, has said he won't enter his 3-year-old filly in the Breeders' Cup because the races are being run over a synthetic surface, which he dislikes. He also hinted that his star likely won't race again until next year.

Rachel Alexandra has won nine in row, including victories over males in the Preakness, the Haskell Invitational and the Woodward Stakes.

The 5-year-old mare Zenyatta is 12-0, mostly over synthetic surfaces. She has yet to run against the boys.

If both horses run in the 1 1/4-mile Classic, the winner's share would increase to $3.7 million from $2.7 million.

"Racing fans around the world have made it clear that they would like to see Rachel Alexandra and Zenyatta face each other and the best horses from the U.S. and Europe in the Breeders' Cup Classic," Breeders' Cup Ltd. president Greg Avioli said in statement.

"While we respect that the race has not been under consideration by Rachel Alexandra's connections, we wanted to make sure that the Breeders' Cup did everything in its power to make the prospect of competing at Santa Anita in November as attractive as possible."

Top female horses rarely run against the boys in the Classic; instead they run in the $2 million Breeders' Cup Ladies Classic, which is scheduled for Nov. 6. Champion mare Azeri is the most well-known female horse to run in the Classic, finishing fifth behind Ghostzapper in 2004.

This is not the first offer to get Rachel and Zenyatta together.

Last month, online wagering services TVG and Betfair Ltd. offered to up the purse of the Beldame Stakes at Belmont Park on Oct. 3 to $1 million from $600,000 if Rachel Alexandra and Zenyatta are in the starting gate.
