ARCADIA, Calif. - If he lets his emotions show, Tiznow will go into Sunday's $500,000 Goodwood Breeders' Cup Handicap kicking and screaming. Not that there's anything wrong with that. Tiznow's competitive spirit is coming back. En route to the track for a workout Monday at Santa Anita, he lashed out with his left hind leg and cut the left hind leg of the pony who was accompanying him. The thud was sickening.
