ARCADIA, Calif. - It never rains in California? Yeah, right. Boy, don't they warn you. It pours. Man, it pours. Twice last month, Saturday cards were washed away here at Santa Anita because heavy rain left standing water atop the synthetic Pro-Ride surface. On both days, major stakes for 3-year-olds were scheduled. The first time, the Robert Lewis Stakes was brought back a week later with five of the eight who were originally entered, and Caracortado prevailed.
