It's not that cut and dry. Exceptions are usually made with derby horses.

It's odd that Albarado would honor the commitment on a horse that, in all likelihood, goes back to Bejarano when he returns.

This, to me, is what stood out...

"Albarado also was the most recent rider for Carroll's other Kentucky Derby prospect, Blackberry Road, who will run in the Illinois Derby or one week later in the Arkansas Derby at Oaklawn. Regardless, Blackberry Road will get a new rider, Carroll said."
