Borel made it clear that he was going to ride the filly in the Preakness BEFORE he won the Derby.

Borel made it clear that he was going to ride the filly in the Preakness BEFORE he won the Derby.

I'm no horse racing expert so I could be mistaken here but from all the pre race chatter I saw on NBC this afternoon they showed an interview with the filly's FIRST owner (and Calvin was standing there) who said the filly would not be raced in the Preakness as it was his belief that female horses shouldn't compete with male horses (or something to that effect). Then in the last two weeks that owner sold the filly who and THAT owner did decide to run her in the Preakness. It was then that Calvin had his first opportunity to consider riding her in the Preakness. Or did I miss something?
