(WHAS11) -The owner of the Derby winning horse is talking about whether he's working to keep the Oaks winner out of the Preakness.
Rachel Alexandra was not nominated to the Triple Crown by her previous owners, so the only way the horse can get into the Preakness is if less than 14 nominated horses are entered, and if her owners pay a supplemental fee of $100,000.
What makes this especially interesting is that jockey Calvin Borel, who rode both the Oaks winner and Derby winner, announced earlier this week that if Rachel Alexandra is in the field, that's who he will be riding.
The co-owner of the Derby winner Mine That Bird acknowledges that he had spoken to other owners about entering additional Triple Crown nominated horses to try and keep Rachel Alexandra out.
But in an exclusive interview with WHAS11's Danielle Santoro, Mark Allen tells us he's changed his mind about trying to squeeze out the filly.
"I thought about it, but it wouldn't be the right thing to do," says Allen
If 14 nominated Triple Crown horses enter the Preakness, Rachel Alexandra is out. Mine That Bird's co-owner Mark Allen has one other horse nominated, a maiden named Indy Express.
"I thought about entering this maiden-trying to keep her out so I could get Calvin Borel back to ride," says Allen. "But that wouldn't be right, so I'm not going to do it. So I'm entering Mine That Bird and I'm not entering nothing else."
But even if Allen only enters Mine That Bird, there are still 400 horses that have been nominated.
And according to blood horse.com and Thoroughbred Times, Allen has called other owners asking them to enter their nominated horses.
Here's what Allen told us when we asked him about making those calls:
"I'm from New Mexico, so I don't know a lot of these other owners they've been in this game a lot longer than me. They got to do what they got to do. I'm just going to worry about Mine That Bird. The other owners, I don't have no control of, and I don't want none."
Allen also told WHAS11 that if Rachel Alexandra does enter the Preakness and he loses jockey Calvin Borel, Mike Smith will be the rider for Mine That Bird.
