Zenyatta profile to air on '60 Minutes' this Sunday

Zenyatta will be profiled on the CBS program "60 Minutes" on Sunday ahead of her attempt to win back-to-back Breeders' Cup Classics and end her career a perfect 20-0. In a preview of the segment, jockey Mike Smith says that if she can accomplish that feat, "she could arguably go down as one of the great, if not the greatest, horses of all time."

"Better than Secretariat?" asks interviewer Bob Simon.

"Well if we can pull it off she's never been beaten, so how can you argue with perfection?" Smith replies.

The segment will air at 7 p.m. Eastern on Sunday.
