O’Brien concerned over fitness of Starspangledbanner

Aidan O’Brien will keep a close check on Starspangledbanner’s legs ahead of his intended run in the Breeders’ Cup Turf Sprint at Santa Anita on Saturday.

The Irish trainer admitted slight concern about the six-year-old but hoped the problem would be successfully treated.

“Since he arrived here, all four of his legs were a bit humid, which is because he didn’t get to do much walking,” said the Ballydoyle handler.
