Ready to rumble. Two of the nation's best 4-year-olds, California Chrome and Shared Belief, will squre off at Santa Anita Park tomorrow. Hall of Fame jockey Mike Smith will ride Shared Belief. The two horses finished third and fourth in last fall's Breeder's Cup Classic. So this rematch is highly anticipated in tomorrow's San Antonio Stakes. See also Pasadena Star News, p.
