Super Ninety Nine, the pre-race favorites in Friday's $500,000 Breeders' Cup Juvenile Sprint, has been scratched after sustaining a scrape while moving about in his stall at Santa Anita Park.
Also scratched Friday morning was Worth Repeating, one of the top contenders in the $500,000 Marathon.
Super Ninety Nine, trained by Bob Baffert, was lying in his stall and apparently stumbled getting up and panicked.
"I'm really upset," Baffert said. "He's scraped up; it's not serious, but you can't have stuff like this prior to a race like this. He'll be OK, but not today. It is really too bad. He was going to win that race."
Worth Repeating was having an issue with his left front leg after training on Thursday.
